Our betta Tiepolo recently had tail biting problems (see my other posts). He started biting his tail after we put him in his new 5 gallon tank.
Water ph, ammonia, nitrate/nitrate all fine and he has heater and filter and lots of decoration/silk plants.
We then took him out of the 5g tank and put him in a hospital bowl to do 100% water changes daily, because the tail biting also caused fin rot.
His tail finally started to grow back after 2 weeks.
So we put our little guy back in his 5 gallon tank and
he started to bite his tail again!!
(He didn't do that in the bowl)
What can we do about it??????
Does he hate the 5gallon tank?????????????
He's back in the bowl now, because I don't want him to get fin rot again.....
