I really did not expect this, I am so sorry hearing about this news!!
But, these guys are good on recovery but just need observation that he is not getting any infection on beaten/torn parts!!
I really feel pain about the hospital things, getting all guys out, rearrange the things! And healing FH!
I really like to work on tank work, decorations, water changes, but not the other part around when FH is sick or beaten up..
We all will consider as lesson learnt!
Salt in water is preliminary thing to help him healing....
wish you all the best!!!
