The last of my trio of cacatuoides has passed on of old age (had them for nearly 3 years) and so I'm looking to add some more apistos. It's a 33 gal planted community tank and although I enjoy watching their mating behaviours, successful spawns are not a priority. What would be some good choices for apistos that would do well in my water: pH 7.5 / GH 8 / KH 4. Rather than attempting to alter my water any further, I'd rather get fish that will do well in it "as is". The current stats are extremely stable. I know that cacatuoides and borellii should do well but are there others?
