Hey everyone I need help my silvers fins are very damaged and not sure why. I don't know how to fix this problem either. He currently is about 8 in. long in a 125 gallon tank with one pleco and one pictus cat. I change water about once a week and water temp is 82 don't have water parameters yet due to just changing it. I have one Rena xp3 filter and an xp4 on the tank. Has an air bubbler and one power head to increase top water movement. Any and all help would be appreciated I have also attached pictures. <br />

The pH is probably to high causing the fin damage , you need to test your water asap and get the P's , water changes won't help raise your pH if it is that

Either fin nipping or water quality issues . tank cycled?really need to know your parameters to help.what percentage water change.how often is "about once a week"? When you turn the tank lights out watch the tank at night , a lot of cats are nocturnal possibly nipping your arrowanna at night.but my money is on water quality

From those P's I'd say its more likely fin nipping like Will said or it could be finrot w\cs won't kill the bacteria it needs treating with appropriate mediation
