Ao I've recently started breeding and growing plants. I was lucky and had an acquaintance give me a 55 gallon he wasn't using anymore. I segmented it into 3 compartments with plexiglass which I drilled tiny enough holes to let water breath thru but not let fry get thru. Anyways I have turned this into triple 16 gallon enclosure that uses one Tidal 55 and couple of sponge filter. Have 2 Sicce heaters at each end to keep it warm. I am putting all my overgrowth of plants for selling plus I have a breeding pair of Neon blue acaras that drop 700 plus fry every 30 days like clock work. These all go into the 55 when rdy ( after 2 weeks). Have already started taking orders on Java fern, cabomba, tiger lotus, Amazon swords, plus the fish, as well as some other fish that are starting to pair up. May have gotten my hands on another 75 gallon as well which I may do something similar. Fortunately the tanks were free and the rest I already had. Now its just hurry up and grow LOL
