The Marine Compatibility Guide
Comparing Marine Aquarium Species
Welcome to the Marine Compatibility Guide which has been designed to help you to find compatible tankmates for your saltwater fish based on your current marine aquarium setup.
The guide is made up of three main sections, each of which can be accessed via the main menu at the top of each page or by using the quick tools further down on this page. The three main sections are...
Species: Containing descriptions and vital information for hundreds of species of marine fish, invertebrates and corals, this section also lists some common names as well as showing some popular tankmates.
Compatibility: Find out instantly if two species are generally known to be compatible. Displays the parameters of both in an easy to read table. You can let us know whether you think the species are compatible and see what others think.
Tanks: Create your own by setting the size of your tank and adding species to it. The guide will then display any known issues and show you tankmates based on the filters you set.
We hope you find this guide useful and please leave any comments you feel may benefit others. Also feel free to contact us with any feedback you may have. Enjoy!!

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.

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

Great spot lapang71! I have set all combinations of shrimp and fan worms to 'compatible with caution' and set these guy to 'not compatible'. Thanks

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 :-)

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.

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? Thanks, Nikki.

Benno, it's called an Eibl dwarf; comes from its binomial name.

Hi ReefDog, 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 :-)
