Hi There-A buddy of mine is getting out of the hobby and has a breeding pair of discus he wants to give to me. I have access to one of those old school 2 compartment acrylic aquariums connected by 2 tubes. The dimensions of each compartment is around 22" Across x 13" Deep x 20" High = about 24.75 gallons. Though I've kept South American Cichlids for a long time, my experience on Discus is a bit light. I tend to like to give my fish more roaming room, but read somewhere that 10 gallons per adult Discus is good. The 13" depth does concern me a bit though. Can a few of you chime in and let me know if this would work? Thanks
