I have Exodons, they are very interesting to watch. How about a solitary Piranha like an Elong or Sanchezi. They can be very aggressive, and live in a 55 gallon for life.
Personally i think Bichirs are pretty cool.
not sure if a 50g is enough for one but it maye be possible.
just something to look into.
Myself i would go with JD's.
I want to grow plants have the designs for the tank drawn up and ready so big cichlids would dig the plants up wouldnt they? was really considering a baby dat and using the tank as a growout, opinions?
if i was to get a baby dat as a solo specimen how slow do they grow as id only keep it in there till it was 8-9'' buying at 3-4'' if i can. how long would i have before looking at upgrading
