At the moment I have 5 Hujeta Gar (From 3" to 5"), a tiger shovelnose cat (around 5"), a Jardini (4") and two VATF (around 5"). They get along pretty well and there hasn't been any problems. I was thinking about moving the jardini to a seperate tank and putting in a Armatus or maybe 2. Do you think this would be a problem?
