Busy Aquarium

Catalina is another beautiful possibility for a 55, I've had one for about two months now. Keep in mind it's life expectancy will be shortened at normal reef tank temps as they are cooler water fish. In the wild I believe they're found in waters in the 62-70F degree range, so even 75F is warm for them. I keep my tank at 77.5-78 all the time. The one I purchased from my LFS(my avatar pic) was actually trained to eat small sinking pellets! I don't feed my tank pellets but he loves mysis and pods! He's fairly active and darts about the tank all day looking for anything in water suspension that might be food. Just provide lots of hiding places for retreat if needed. Mine sleeps in the rocks.

 

Catalina Gobies are cool water fish so not in your tank if it is tropical.

 

Wow, dont remember reading that. Thanks for the info!

(sorry, sometimes tapatalk will pick words for me!)

 

stocking tanks in LFS can keep large numbers of these together for the same reason yours haven't killed each other yet... due to being overcrowded and no places for territories to be made, the aggression is limited... when you move these to a 210 and set up rock work, expect territories to be established and your numbers to diminish.

I tried to keep three firefish in my 120 and they killed each other off until there was one left... that was two years ago and I still have this fish. I was told they were ok to keep in numbers, but this is definitely wrong.

 

that makes sense, before I had 1 firefish and 1 scissortail and they got along fine. I'll just keep it to one of each species of goby instead of multiples.
