Apisto Cacatuoides (School of 4)
Juvenile Cacatuoides (or Cockatoo) can be hard to sex. To ensure a nice mix of sexes and to keep these little dwarf cichlids feeling more at home, a small group of four might be a good purchase for a larger community tank.

I bought a school of four Apisto Cacatuoides for my 30-gallon community tank. They’ve been active and peaceful since arrival. The males don’t fight much, and the coloration is vibrant. Easy to feed with flakes and occasional frozen foods. A great addition to a beginner-friendly setup.

These fish are small and colorful. I mixed two males and two females, and they’ve coexisted well. They don’t require much attention, and I noticed they’re very active during the day. Just make sure the tank has plenty of hiding spots to reduce stress.

Perfect for a small tank. The fish are lively and stay calm even with other community fish. I’ve kept them for over a year and they’re still healthy. The care level is simple, and they thrive on a varied diet.
