As stated in title, I have a 4 year old 5 inch ryunkin goldfish with strange growths on his skin. He is housed in a 300 gallon outside tank with 1 10 inch koi and 4 other 4 inch comet goldfish.
The tank is filtered with a homemade trickle filter that is fed by (I think) a 500+ gph pond pump bought from Lowe's. The pump has a prefilter that screws on that I clean twice a month to remove debris.
I haven't tested the water for nitrates/ammonia here lately. The tank has been set up since 2006 and I empty the tank about 25% twice in every season, refill it with dechloronated water, and add about a cup and a half of salt. No new tank inhabitants have been added since the initial setup in 2006. The temp of the tank is roughly around 50-59 F currently. There is no plants currently in my tank. The tank recieves natural sunlight but is mostly in the shade to prevent excess algae growth. The tank is bare bottomed that is covered with algae. The fish are fed a diet of Laguna pond fish food once to twice daily and are not fed below 50 F.
My Ryunkin developed these strange growth's that I think are tumors but I am not sure. I am away at college and I come home to do maintanence and I noticed the growths on Orangu when I was doing a partial water change. I would like to get another opinion and what's the best way to go about treatment or if there's no hope what can I do? He acts normal, eats, swims, and chases the others like a normal goldfish.
I have treated him once last month with a parasite treatment that had a small percentage of malacyte (spell check?) green in it and it seems like it hasn't done nothing for the infection. Here's some pics when I had given him the treatment.
What are my options to save my Orangu?
