My betta had a small bump on his chin. this has now turned into a puffy small hole that doesnt bother him (he doesnt rub against objects or have any unusual behavior). and i am leaving for a 8-day cruise tomorrow morning!! what can i do? fyi he is recovering from fin rot, and i am treating him with melafix. I am pretty sure this hole is not good, and i looked up hole in the head disease but this isnt around the eyes like HTH. the area around the hole is raised, like a crater. please help! thanks!
pictures attached! it took me so long to get him still :swear:....sorry they are dark. if you tilt the computer screen down it gets a little clearer...
