Hello!
Guess what? You've done exceptionally well so far! Congrats! I think my lotls have about a hundred lives because in my first month (they were only a few months old), despite all my research and wanting one for TEN YEARS before I finally got them, I screwed up A LOT. Ha. But my guys are happy and healthy and HUGE and loving life, lucky for me I learnt from every mistake xD And my pretty boy is now a year and two months and my golden girl is a year on one month old

Many more happy years to come! :bowl:
So let me share my knowledge so far

Floating? Nothing wrong with him. He has gas/needs a poop. My old flatmate had a golden that ALWAYS got gas. A lot. Most days we would come home from work and his bum would be floating and we would just say "Oh look. Raro needs another fart.." Unfortunately, As far as I'm aware there is no way to burp a lotl so he had to live with it. Luckily hes grown out of it

If it was to persist for more then two days continuously then you can fridge to help him pass it. On that note has anyone else ever seen an axolotl fart? We saw my pretty boy fart ONCE.

It was the funiest thing we had ever seen! Just like a cartoon - a cloud of brown exploded out his butt into the water.It dissipated pretty quick but we couldn't believe there was a fart cloud! Haha!
Anyway, back to you. The gill filaments or "fluffy" part will definately regrow and having little or no filaments won't harm him. He won't suffocate and die from it, trust me! I wouldn't worry too much about him, sounds like hes just being a special child haha.

Do keep an eye out on him though and report any worries you have. It might seem silly and result in nothing but better to be safe than sorry.
