So the long story is that I needed a cichlid growout tank, to find a couple of cichlids I could eventulally put with my oscar in a 150 gallon. Originally it had been a 40gal breeder, which had a Peruvian Severum, a Firemouth, and one of the Petsmart "Red Texas", that I had thought was a mislabeled Green Texas, but was actually a FH. He kept the FM and the Sev hiddn all the time. So they left him (he is much happier solo; which is how I think I will kep him after how I've read finign tankmates for them is a truly difficult matter) and went into a diff growout tank, a 55gal, along with 7 Tiger Barbs as temp dither fish, plus a Convict and a Jack Dempesy. These two latter ones are about an inch long, and both happy to go where they please, which is funny based on their size. They do stick around each other, so I wonder if they're friends? But anyway, the Firemouth is about an inch and 3/4 long, and he started getting braver after a few days. He lets me see him and watches me back, he only hides really when I move too quickly. The Sev however... he stays hidden only marginally less than he used in the 40. And he hasn't colored up like he was in his Sev tank at the LFS. He is the biggest one in the tank, about 2 inches, possibly 2 and a quarter (and from what I had heard that I used to base my stock list, they are normally more peaceful than other cichlids, but have their size to back them up against others). There are four caves, and two other sort-of-cave-things in the tank. He has taken the biggest one with the most entrances, so that's where he stays.
TLDR version: What size tank is big enough for either a Sev growout, or big enough for his adult size? What, if any, tankmates could he have that might make him less scared (in either these two tank options)? Or is this a temporary thing, and how long should I wait before I get him out and into somewhere else?
