pbnj Posted August 29, 2010 Share Posted August 29, 2010 For those of you considering adding a school of chromises, you may want to reconsider. You'll hear some say most of their schools die-off while others say they still have their entire, original school. I just read somewhere that these fish do well in schools as juveniles, but then they pair-up as they mature, so you can see why some people are succesful and others are not. Then again, you could get lucky....just sharing what I read. Quote Link to comment Share on other sites More sharing options...
chrisfowler99 Posted August 29, 2010 Share Posted August 29, 2010 Something to think about. I definitely want to get some schooling fish when I setup my new tank. I had been assuming I'd go with Chromis...maybe not. Quote Link to comment Share on other sites More sharing options...
mFrame Posted August 29, 2010 Share Posted August 29, 2010 We had a group of 5 that we started with when they were fairly small. Individually they weren't aggressive, but as they got bigger they would rule the tank as a school and were very aggressive toward the other fish in the tank. Additionally they would hog all the food when it hit the water. We paired it down to the three smallest ones and that has helped quite a bit. I'd say for a 90g tank, though, that is still the most you would want if you like having other fish. Quote Link to comment Share on other sites More sharing options...
Derek Posted August 29, 2010 Share Posted August 29, 2010 I've experienced this. I had a school of 15 blue green chromis. I ended up with 2 in the end. Quote Link to comment Share on other sites More sharing options...
