I've had a stiphodon goby in my tank for over a year and i pretty much don't feed it and its belly is nice and round.
i think it just eats biofilm and left over food from my other fish but I wanna get more of them cause I love watching them hop around the tank and stick to the glass, rocks and plants.
what should I feed them?
I'm probably gonna get like 2-3 more for my 10 gallon is this a good number or how many do you think I should get?
