my channa decided to jump out of aquarium whilst i was at work, and was out a gd while! But i got in put him back in tank, and he LIVES! .... He was covered in fluff and dust dried up and looked dead! But as soon as he hit water started swimming! The thing im worried about is, will he be ok!?!?! He looks a bit rough but is swimming and roaming the tank fine? Anybody give me any advice on how to keep him alive or healing him up please!?? And ive blocked the gap up he climbed out of by my filter tubes. Thanks in advance!
