Ok.. this is going to be long.. sorry but I'd like to explain everything at once. If you get confused look at my sig its got pics of everyone so you can put a face to the names LOL
Ok so I have freddie (my avatar) who is a chronic tailbiter. No matter what I do he bites. Well I went away for two weeks on christmas and did not feed the fish and only had my roommate check the temps and do a small water change on my 3 gallon.
When I got back both fish (orange one) and Damon (red one) were very thin and discolored. Fish had to be put in my hospital bowl he is so lethargic.. its my fault for not thinking a fish his age would not do as well being neglected so long. (I didn't have anyone trustworthy to feed and clean water). I did big wcs on all tanks and gave a small meal.
Now onto my real story. Freddie looked great. His tail had a lot of new growth on it (its been almost a year of him biting his tail) and his color was good. I fed him etc just like the others and woke up this morning and his tail was shredded once again.

(Let me say there is nothing to tear his tail.. I've checked thousands of times).
Why would he be happier with only light from a window and no food than food and light and interaction??? (BTW I've tried numerous things to find the source of the biting.. nothing).
Well now I have this minibow tank that was going to be for blue jeans (blue/white one) but I'm thinking of putting freddie in it and sort of ignoring him to see if he really does like it. I have reservations about taking him out of five gallons and putting him in two but if it makes him happy I'll do it.
Do you think I should down grade Freddie into 2.5 gals and give BJ all 5? Do you see something in my leaving that I could do all the time to keep him happy?
Any advice, tips, questions.. I'll answer. I really want to do something soon.
Thanks... Jackie
