his tail is blue but he has a lot more red streaks in it, this morning his tail is shorter, yesterday it looked shredded, this morning all the raggy ends were gone, it looks even as if you cut it with scissors, the one on his back is way shorter today too, he has no red on his body, just his tail the one on his back, he is eating really well, and has an enormous bubble built, swimming around, and comes right up to you when you look at him, but his tail is getting shorter, I put more betta fix in this morning but didn't put any more salt in. Should I get more stuff, he is constantly going under the filter, do you think it is ripping his tail by the suction.
