We've had this goby for over a year, and in the last 10 days or so it's not eaten much, but it's belly is very big. Could it be some kind of internal parasite? Should we medicate? I have on hand fenben, kanaplex, and metroplex, but it's not eating much at all so I am unsure if I can get a theraputic dose of anything into it. (We also have some other medications on hand, that I don't think are needed like RallyPro, copper, and nitrofurazone) We have ordered prazipro and focus, but they will not arrive until Wednesday. Thanks for any assistance.
