Hello! I just added my GT and my Jag to a 300 gal tank. The only tankmates since it is new are two large silver dollars. The tank is 8ft long with lots of rocks and wood. They have only been in for a couple of hours and already they are both scratched up (GT is wearing the worst of it) from mouth fighting for dominance. Unfortunately at this point I have no other large cichlids to add to the tank to distribute aggression. What should I do? Let them sort it out? Move the GT back to a smaller but safe tank? The only other tankmate I could add at this time is a 15 inch redtail - shovelnose cross catfish. Looking for some good advice. I don't want my GT killed. Thanks for your time and ideas.
