My friend's dad passed away in the middle of cleaning the main tank, so these guys were stuck in a 55-gallon for months. There are two full-grown plecos and 5 cichlids, so the 55 they were in was definitely too small. My buddy asked if I wanted them, and I agreed, but I didn't realize how aggressive these guys are. The one frontosa that likes to hang out by the top left of the tank was picked on so bad that his fins are all ripped up, but he still tries to eat when he's not being bullied. I'm curious as to what the 2 white species are and if they are more aggressive than the frontosa. It's weird though; yesterday I put them in this 125-gallon, and the healthy frontosa was beating the hell out of the sick one until the next day. The white ones seemed to take over the tank, and now the healthy frontosa is staying down in the bottom right of the tank leaving the sick frontosa alone for the most part. I plan on moving that 55-gallon to my home and isolating the injured one asap. Any advice is welcome.
