I have asked before but I didnt get the best answers. I have my rtc x tsn in my 55 gallon and I will be moving him into a 150 in about 2 months and was wondering if I could keep a fire eel with him in the 55 and then when I move the hybrid into the 380 tank I would move the eel into the 150. Could I do this? And what else can I keep with the hybrid. I am getting an rtc next week but I dont plan on getting a tsn. Also could I keep a lince catfish (Platynematichthys notatus) with him or how fast do they grow? I really like rare fish so any suggestions?
