Hello all, my arowana has what I consider to be rather drastic split pectoral fins and I'm looking for advice to help heal them. This has been an ongoing problem and I'm not sure what else to try. He's in a 240 gallon with good water, 0 ammonia,nitrite. 5ppm nitrate. I've been using the pozzani nitrate removal filter for water changes. Temp=29. I'm currently trying to get him on pellets. Atm he only eats dam mealworms. I want him on pellets due to nutritional benefits. I've tried adding salt but this did nothing to help. Any advice most welcome, thanks for looking.
