Hi everyone, I used to use this forum years ago and am no beginer. I have been keeping betta fish for over 6 yrs and never had this happen.
I set up a 3 gal betta tank (my smallest ever) that was supposed to go with me to my college dorm this fall about 3 months ago (small dorm, small tank). Everything was great until ago a month ago when I noticed his fins started to detoriate - big chunks missing. The tank parameters are perfect and I had fin rot with bettas before - this was not it. Obviously it is either something in the tank riping his tail or he is fin biting dramatically.
It seems to only get worse and more than half of his tail fin is gone now (the dorsal and analfins are not very affected).
I removed all potentially damaging objects but doubt they were causing the rips (smooth driftwood). I added a large ceramic jug to give him a good hiding spot if he is feeling stressed but it doesnt seem to be helping.
Whenever I go up to the tank he agressively paces back and forth, it is difficult to get him to eat since he will get caught up in this pacing and flaring. I also noticed white lines on his gills which I surmise are from the frequent flaring.
Obviously I need help with this and am wondering the following:
- Could the small tank size be a stresser? My other two bettas each have 20 gals but he was supposed to come with me to college but perhaps I could move him to a 5 gal? (the tank is new and i love it though so if there is any other ideas let me try that first)
- Indian Almond Leaves? Never used them before but maybe this betta is just neurotic and needs to chill? Also I know it would greatly help regrow his fins.
- Could the tank layout/lighting/filter be an issue?? Perhaps he needs more coverage or swimming space? The light is too bright? Or MAYBE the filter could be catching his fin (the flow is so light though and I looked at the intake and there is nothing to rip them)?
if you have any ideas please help I really love this guy!


also the layout used to be way cuter before the jug and he seemed less stressed but his fin was still deteriotating so maybe the layout is an issue?
