My dad recently gave me his 100 gal tank that he custom built himself It has a sump filter because this used to be a saltwater tank. It has been a long process getting this hosed down, leak tested, and aqua scaped. Currently It has 2 BN plecos and 4 mollies. The temp is usually at 77F with a slight difference from time to time. The substrate is floramax.My goal is for this to become planted but my wallet does not agree with me at the moment I was wondering what fish I can add once cycled. I want bottom middle and top dwellers so the tank has activity. Any suggestions,comments, and concerns are welcome Thank you!
