My plan is to keep them in a 5 foot tank, although it will be a bit narrow - only 30 cm - about one foot, hope that it'll work since it's around 60 g. Interesting that you mentioned Metriaclima as tankmates Matt since I was thinking of getting Red zebras but wasn't sure if they would hybridize so I was thinking of keeping them by themselves. Another option was keeping N. venustus with them but I don't think the tank will be big enough for those. What do u think? Any suggestions on numbers of red zebra or N. venustus, if it is possible to keep them in a L5'xW12''xH20'', if I keep one male and 5-6 females of M. auratus.
Everybody says they're PITA to keep because of how aggressive they are so I'm still not 100% sold on the idea.
