I have a 9" umbee growing out in a 240g solo. I recently got a 6" LSN catfish and I wanted to put the two together. What do you guys think my odds are of keeping the LSN alive with the umbee? If there is no chance I'll just keep the LSN in my 180 with my oscar. Last growout/tankmate my umbee had got killed when he started to grow his teeth, but it was a docile arowana so I don't know how he will react to a bottom dweller.
