I am so frustrated. I have a guy that keeps getting red streaks in his tail (he's opaque white so they really stand out) and have had to take him out of the divided tank he was in to treat with aquarium salt and higher temps. Then one of his tank mates started biting his tail. And I can't seem to get a cycle in the tank so I'm going to put the remaining three guys in their own containers to do a fishless cycle and get it stable. Now I come home and two of my other guys (in a divided 6.6 gallon) have complete bit the edges of their tails! One started biting a little bit since I had to change filters and he was IN LOVE with his old filter. The other guy was FINE this morning and now his whole white edge is GONE (and I caught him biting when I got home, it's definitely not rot). He was a mustard gas butterfly and his white edge is no more. The only thing I can think that would have caused him to do this is that I didn't feed them this morning. I was going to change to once a day so I skipped this morning and it must have really ticked him off enough to eat his own tail. I am so tired of playing fish psychologist!! GRRRR!! I feel like the troubleshooting is never done! And I miss all of their beautiful tails!
What am I doing wrong?? Why is all of this so difficult??
