Anyone have any experience with firefish? I want to add some to my tank. Can 3 get along fine? I want them to sorta school cuz I think it would look pretty cool. I heard they are jumpers so are glass tops ok?
The glass top won't hurt them because there isn't much space between the glass and the water level. I have had experience with them a few times, but I've lost all of them to jumping out, so now I have a mesh top that I've replaced from my glass top.
However, the glass top will restrict light to corals, keep in heat and prevent gas exchange and you will have to clean it very frequently to deal with the salt creep. Make a mesh lid, its very simple to do and MUCH better for your tank.
Piggybacking on this thread - how well do firefish do in pairs? Any risk of them fighting? Can I get one purple and one pink or should they be the same color?
Yes, three is a small group, I'd say. I've heard a couple stories of firefish being aggressive to one another, but honestly that seems really rare. They are such docile fish.
Firefish are jumpers only when stressed. To reduce any stress put many crevese to hide in. three will do fine if in a 40 gallon tank and introduced at the same time!
(Nemateleotris decora) good luck!
