The Red Line Barb is a new fish to me, since I've been out of the hobby for approximately 15 years, but I have seen one at a hobby shop demoing a planted tank. It only has one in it but that one fish is a fine looking fish; it grabbed my attention right away. Started trying to remember if I had seen it before but couldn't recall so, apparently a newer specimen into the hobby world since roughly 1999.
I have considered a used tank and probably will pick one up, something around 20 gallons to act as my quarantine tank. I was at a thrift shop today, I'm at my other home on Vancouver Island in Qualicum Beach and I hit the thrift store for cheap magazines and books to read. They had a 30 gallon for around $25 and if I had my main tank I might have bought it, but I know tanks at thrift shop are a dime a dozen so I'll hold off.
I haven't been to Aquarium West in over two decades so I was at their new store yesterday and they have a Fluval Osaka 260 set up I think I'm definitely interested in, its a 57 gallon and the dimensions are decent and could handle 4 Red Line Barbs, some other smaller barb schooling, some Panda Cory's, some shrimp, and with that I think I would be good to go. The dimensions of the tank is:
40.5 inches long
17.7 inches wide
24.5 inches high
Its 4.5 inches longer than the 50 gallon I was looking at, with the red line barb I think I'd be better off with the slightly longer tank.
Thank you for all your kind responses, looking forward to my "new" life in the hobby.
