My betta Bob seems to have a fin problem they keep on getting smaller and smaller (especially his tail). Idunno whats wrong this is the 2nd time ive done bettamax on him...

Could be fin rot.Kind of just melting away? Do you see black or red coloring on the edges?

How much water do you change out each week? Do you test it?

I saw red edges a while ago now theyre greyish... I change about 25% of the water a week and all the water parameters are normal as of my last test... I need to buy more nitrite/nitrate test strips.
