I’ve posted before with questions about a sleeper goby and the care for it, with lots a help and support, I’m wondering now, if a sleeper goby or water cow would be compatible with a gulper catfish as I believe that I saw a picture on here, depicting a setup with such. (I believe it was by SharptoothBass, sorry if I butchered that) I currently have a number of 20 and 40g tanks. I understand that the sleeper should have a much larger tank and was wondering if 75g would suffice? I’ve read multiple threads on Gulpers and have seen that one can suffice in a 40g breeder tank so that should be enough but I worry about the size requirement for the sleeper goby...? Any help would be much appreciated.
