Do you have a betta fish or gold fish?
I don't know what to do with mine, I think he's dying.
He hasn't eaten over the last few days, but looked fine, but just sat on the bottom of the tank. I cleaned his tank out tonight and he's like mouldy and his fins are in an awful state.. It come on really quick
I think he has columnaris or a fungal infection...
He has a heater, filter etc. I change his water regularly and put betta conditioner is his water. He's in a 10l tank by himself.
What should I do? Should I put him down? If so, how? Or what should I get him from the pet store? He's in a pretty bad state
