I know I'm loving the bars lol and yes the fin damage looks bad. I literally witnessed the Escondido bite a chunk out of the fin. They literally just keep going at it and its confusing. The flowerhorn keeps acting like its laying eggs but I don't see anything.
You may need to decide which fish you like better, the FH or Texas, and get rid of one. I personally would not tolerate fighting that would cause a fish to get serious fin damage. I just don't think that's a good way to keep fish.
Also, you should report Ihsnshaik to the administrators and let them deal with him. He is clearly out of line. Engaging in a back and forth with an immature child makes you look almost as bad as it does him.
