I never really cared for plecos but last week i went to lfs and I fell in love with this royal plec what a pretty looking plec . I just got him some drift wood and at night i put frozen peas alge wafers and shrimp pellets he eats like a pig but he has a sunken belly and stringy poop so im sure its a parasite just treated one of my oscars for it is jungle labs parasite clear a good med and how much of the dose should i give him I now plecs dont like meds . Any other info would be great hes about 5 6 inch paid 29 bucks hes in a 100 gallon with two oscars so im used to messy fish how big do they really get ?
