Ok i have a well cycled 5.5 gallon tank with about 8 lbs of LR and about 10 lbs of LS. I need help selecting an easy to take care of goby or gobies. Thanks
Personally, I would limit a tank of that size to 1 fish. If you want a goby I would try one of the smaller species like a neon goby, barbershop goby or twin spot goby. In any case you would still have to keep optimal water conditions and make sure the tank is covered if you keep a barbershop goby, since i've been told that they can jump!
If it's a Neon, make sure it's captive bread, not wild caught. The wild caught ones don't survive.
I have a Tiger Goby - 1.25". Not real colorful, but great personality.
