CrooK808;4841602; said:Oh yeah. even though certain gobys are brackish water. at the petstores i see them in freshwater. so my question is do i need to keep them in brackishwater ?
Juxtaroberto;4841630; said:Yes, they need brackish. People who keep them have said that in freshwater, all they do is hide, and seem easily stressed, while in brackish they become inquisitive and outgoing. I think this is a really good indication that brackish is a must.
Also, you shouldn't ever have fish as a "clean up crew." You should have a fish because you like it... and just feed appropriately and vacuum the substrate yourself. Adding fish just adds bioload.
