Hey all, in the future( after I finish using my 5 gallon for a QT tank) I was considering getting Bumblebee Gobies. I know they need a cycled tank and salt, depending on the species( the ones with broken stripes are brackish, right?) and I was considering feeding them Live Brine Shrimp. My question is, how many could go in a 5 gallon? I was thinking 2. Is this an OK amount? Thanks for any answers!
