2 of my fish have HLLE. At first i though it was my cow fish that died because the are poisoness when they die. Then I did some research and found out that it comes from poor water quality and bad eating. Im affraid that I had both, (so much for my mom buying their food at target). I tested my water perams and all were in their correct levels except the NitrAtes as well as my salinity. Both were pretty high so i did a 50% water change with RO wate this weekend. and got them back on their good food from the local fish store. I know vitamin A, C, and B help but can I also get those at the store or could i cut human vitaminds and disolve them in the tank. Im so worried and need some help. ANY THING IS GREATLY APPRECIATED!!:smirk:
