He's skinny. He's eating and getting longer, but he's wasting away. I'm thinking internal parasites. Is there anything in particular I should use? Is there any way to use it without putting him in his own tank (He's 20", it would be tough)?
he's in a 265 and is never bullied, ammonia 0 nitrite 0 and nitrates are a constant 15ppm due to the drip system. Any help would be greatly appreciated.
here is a picture for reference.
