Hello I'm brand new t this forum & what a great resource this has been! I've been keeping freshwater fish for about 15 years. I just set up a indoor pond 400 gallons. I just purchased 4 2.5" Redtail Catfish through the mail. Should be getting them next week. Can 4 of these fish grow up together & coexist in this pond for a while? Also what are some good tankmates for them? TIger Shovel Nose? How about Sailfin Pim, Tigrinis & Marbled Catfish? ow about FLowerhorns & Dovi? I probably won't keep all 4 of the RTC's because feeding them would break me! LOL. How about keeping two of them? SHould I try to find a pair if i keep two of them or should I just keep 1? Thanks for all of your help.
