Betta Fish Help!

It could also be a ph problem, but since this is a betta not a goldfish it probably is a fungus, bettas are more prone. Good luck with treatment. Don't blame your dad though, it was more likely bad timing. In four days the water shouldn't have gotton so bad as to develope a fungus, it was probably already in the process. Oh and you can go off for a week without feeding your fish, that's no problem, its better for keeping the water quality good and probably kept your fish from being worse off.

I am now treating him for Slime Disease, and he seems MUCH better. Ashley, his tank size is a normal goldfish bowl. Is this too small?
Thanks much to you all. I'm now putting in that aquarium salt and a drop of aquarisol, so I'm hoping all will remain well.

How's the little guy doing now?

Some goldfish bowls are decent sizes. I've seen some pretty tiny ones to some that are over a gallon. I have one betta I keep in a 1/2 gallon mainly due to lack of space on the shelf, and because this particular betta is a huge bubblenester and seems to enjoy it. As long as you keep up with WCs, a smaller tank will suffice.

I have used Melafix to help with frayed fins but I guess that I catch it early enough with my beautiful bettas since I am almost always looking at them. I am not that experienced with keeping bettas but a few years ago I managed to keep one alive for about 3 years. I guess always keeping fish medication on hand is a good thing since fish can get sick when you least expect it.
