Hello, first of all, I'd like to introduce myself as a new member.
My name is Michel and I live in the Netherlands.
At the moment I'm in the progress of giving up my L-number breeding and am downsizing my fishroom due to the enormous overhead costs.
I will be keeping my oscars, flagtail, sailfin and panaq pleco's, ghostknives and albino senegal polypterus and they will go in one 500 gallon plus tank that will be setup as soon as the rest of the fish and tanks are sold and gone.
I do have a big problem with one of my tiger oscars. It started with some white spots on his head and side, so I thought hith. Placed him in a hospital tank and asked my son, whom is also a member here for advice since he has more experience with oscars. He told me that at first it looked more like dropsy so I treated with antibiotics. Story is, it is getting worse and his front fins are mostly gone, he's losing scales and slimecoat. Been doing waterchanges to get the antibiotics out of the water and filtering over coal as well. Now I just did another waterchange and removed the coalfilter. But I really need some help with finding out what is wrong with the oscar so I know and with what to treat him.
Any advice on what is wrong and what to do would be deeply appreciated. Anything to save this cuty.
As a note, one of his gillplates was already damaged when I bought him as a 1,5 inch baby.
