Comment left on compatibility of Pholidichthys leucotaenia and Hippocampus erectus
hello.. i have engineer gobies in all my adult seahorse tanks (erectus) in fact in my 120 gallon the 4 engineer gobies are over a foot long now.. when feeding they eat right with the sea horses ..have never had an issue .. in my tanks they make great tank mates for eating the excess food

Comment left on compatibility of Gramma loreto and Pseudochromis splendens
I've had the two together for years, and they get along fine.

Mine, that I own since now 2 years (and is now about 8 inches) , is with damsels, clownfish, Centropyge and Siganus is very kind. It doesn't touch to LPS nor to disk anemones. Not even to the small (1 cm) white starfish which are everywhere in the tank. The only live animal it did eat: snails, they may hide a few days but it always manage to got hem.

Depending on the size of the tank otherwise the Maroon Clownfish eventually will even make it difficult for C. Viridis to come out of hiding to eat. So not for a Cube tank
Comment left on profile of Thalassoma lunare
This is a dangerous fish. He has killed my Yellowtail Damsel, Royal Gramma Basslet, Tomino Tang. Hasn't killed Clarki Clownfish yet, but ate the eyes of the Tang... straight through from one side to the other! He should go in last. If he's already in your aquarium, you will not be able to add any other fish. I have a 55-gallon, FOWLR.

Comment left on compatibility of Canthigaster solandri and Siganus punctatus
I recently introduced a tiny blue spotted toby to a 185 community/reef and my much larger Golden Saddle Rabbit Fish has been completely spooked ever since. He's been hiding for about 5 days now, but oddly he's hiding almost next to the puffer so it doesnt appear that they are fighting directly. I am not sure what's taking place but I hope they come out soon! Everyone else seems happy and healthy.
I have had several of this species of triggerfish and they have varied quite a bit individually in terms of how aggressive they were. One of them was so aggressive that I had to keep him/her in a tank alone because s/he attacked literally any other fish that was in the tank.
I had received the super-aggressive trigger from a friend who was fed up with him/her. I had another one of the same species who was very well-mannered and lived happily in a mixed tank with a tang, an angelfish, and a Sergeant Major damselfish--with absolutely no problems of aggression.
This species of trigger seems to be the least predictable (IMO) as far as how aggressive it might be in the tank.

just make sure to do lots of water changes, the longhorn cow fish will release
a tiny bit of toxins, and since the copperband is so delicate, it has a higher risk of dying, also remember to put the copperband in quarentine for at LEAST 2 1/2 weeks
Comment left on compatibility of Centropyge bispinosa and Abudefduf saxatilis
I bought a Coral beauty and introduce it to the aquarium. Immediately the sergeant major damselfish went into attack mode.
The sergeant was a bit aggressive with a royal grammar but not to the other tank mates (Blue Damsel, Tomato Clown, Diamond Goby). When it saw the Coral beauty "It was on".
I guess they must be the same size (or coral beauty bigger) and introduce at the same time (or sergeant major last) to be compatible.

The Zebra Moray Eel is the most peaceful one & not aggressive. I don't know what site this is but should be removed for posting inaccurate stats.
Comment left on profile of Centropyge ferrugata
the pic on this page looks more like a Flame Angelfish (Centropyge loricula) than a Rusty Angelfish (Centropyge ferrugata)

Hi just wanting to know from people how they keep this fish, and where do u get the copepods etc, ,from australia
Comment left on profile of Salarias ramosus
My Starry Blenny seems rather aggressive. It chases my Springer's Damioselle and wants to take over its territory. In fact, it wants the whole tank! However, it is a fabulous algae eater getting into every nook and cranny that my Yellow Tang missed (no longer have him)
Comment left on compatibility of Pseudochromis aldabraensis and Pholidichthys leucotaenia
My neon dottyback was too aggressive and continually nipped and chased my goby. Had to move the goby to another tank with less aggressive tankmates.
Comment left on compatibility of Chromis cyaneus and Oxycirrhites typus
Maybe others have had better luck. Our Longnose Hawkfish was heavy on the hawk. Any other fish we added to the tank, he would attack and rip the fins to shreds, killing multiple fish until we sent him to live in a tank with more aggressive fish like damsels.
Comment left on compatibility of Diodon holocanthus and Odontodactylus scyllarus
I currently have a 75 gallon tank with 50 gallon sump. I only have 7 inches of water with a 180 galloon rated protein skimmer. Water is clear and the 6 inch clown/peacock mantis has a cave. The 4 inch porcupine puffer travels all over the tank but mainly stays on the otherside of the tank. They currently leave each other a lone. When they do occupy the same spine, neither one bothers the other. The first time they met, the mantis shrimp was currious and annoyed the puffer which inflated partially but since then nothing has happened...yet.

Suggest also picturing the male version of this Angel since it's one of the few genus to have such a stark difference between the two.
Comment left on compatibility of Mespilia globulus and Xenia sp.
My blue tuxedo sea urchin leaves all my corals alone except the pulsing xenia, which he rips off the rock and eats.
Comment left on compatibility of Nemateleotris magnifica and Pseudochromis porphyreus
Hi tripleacres. I'm glad you managed to save your firefish. I have now set this combination to 'not compatible'.
Purple Dottyback is too aggressive for the firefish. My dottyback was already established in the tank and overnight he tore the fins badly on the firefish. Fortunately I was able to just return my firefish to the other tank and it recovered fine. But I would not recommend this combo.
Comment left on compatibility of Nemateleotris decora and Valenciennea strigata
Hi jodyg. I'm sorry to hear about you fire fish :-( I have set this combination to 'not compatible'.
my golden head sleeper gobi showed some strong aggression towards my purple fire fish... came home from work the next day and 1 out of 3 of the fire fish is dead... he is still chasing the other two fire fish when he sees them.... do not recommend this combination
Comment left on compatibility of Sabellastarte spectabilis and Rhynchocinetes durbanensis
Great spot lapang71!
I have set all combinations of shrimp and fan worms to 'compatible with caution' and set these guy to 'not compatible'.
ime, camel shrimp harrasses feather dusters till they didn't have time to open up
Comment left on profile of Wetmorella albofasciata
Hey thanks Hondadude. I have got one now and he is so beautiful. Guy at the store suggested just keeping one of them due to size.
I didn't realise they would jump out of tank, I will lower my water level a little bit then to be on the safe side. Thanks for the tip :-)
Comment left on compatibility of Priolepis nocturnus and Gobiodon okinawae
P. Nocturnus tends to chill under the rocks upside down, whilst the G. Okinawae hovers all around the top of the reef/rocks and into the open water at times. P. Nocturnus will chase the G. Okiawae out from under the rocks if it comes too close but doesn't seem to be aggressive, just territorial about it's spot.
They do fit in an aquarium that size. I would only add one to a 15g especially if its a male. They have a max size of 2.5 inches which is also why I would only recommend adding one. And be careful because they are good jumpers and can jump out of the tank if they don't have a good hiding spot. They enjoy picking their food off of live rock and sand, and will eat small frozen/prepared foods.
Comment left on compatibility of Amphiprion ocellaris and Amblyeleotris guttata
Hey Waa7, that it what the guy in the store suggested so I got 2 and also a spotted goby.
They all get on great; the goby loves sifting the sand :-)
Try get a pair of clowns that are paired that means the fighting is over and they are a joy to watch.
Hey. I am thinking of getting one or two of these for my 15g tank.
Can they really be kept in a tank that size and does any know if they are better alone or in pairs?
Comment left on compatibility of Chaetodon tinkeri and Centropyge potteri
My tinkeri hasn't bothered anything at all. It was on the receiving end of aggression from our tang, but once we removed the tang it just goes about it's business. Not quite the answer you're looking for, but I suspect it'd be fine.
A friend of mine has a 150 gallon tank with a tinkerii butterfly and some gobies in it. He has asked me whether or not he could keep a potters angel in the same tank. I said I didn't know for sure but knew a place where we could find out :-)
The guide says they are compatible but just wondering if anyone had any experience of keeping these fish together?
Comment left on profile of Centropyge eibli
Benno, it's called an Eibl dwarf; comes from its binomial name.
Am sure my friend has one of these but he called it a Weeble Dwarf or something like that if I remember right.
He loved it, said the same as you about it having loads of character :-)
Comment left on profile of Lysmata amboinensis
These guys are amazing, they are so active and friendly.
They come straight to my hand when I put it in the tank, doesn't matter if it's feeding time or not.
What other inverts do people have with these?
Love mine its got so much character, its a very curious little fish, kind of shy, I love the color on it. it seems very docile if you ask me. It doesn't seem to mind being in my 29 gal. Tank . all around a good fish and my favorite dwarf angelfish
Comment left on profile of Lactoria cornuta
I have heard about it but not experience it. I have had 3 of these chaps and not one problem.
They are great fun, come to the front at feeding time and eat from my hand too ha
Comment left on profile of Macropharyngodon bipartitus
I have heard that they stay hidden for up to 10 days. They probably come out at night to check the tank out and get their own territory
May be a few mroe days before you get to see them in the daytime
Well yes they are, look at all those green ticks :-)
Just make sure your tank is 20 gallons or above and you should be fine.
Can anyone tell me if these fish are compatible
How long do these guys hide for when you first get them? I have had mine 5 day now and it never comes out!!!!!
Has anyone ever had experience of a longhorn wiping out a system with their toxins?
