Now that you mentioned the pleco, I'm thinking what may have happened is that the pleco injured my frog's head and it got infected. A small cut could have, should it be infected, turned bad very quickly. Especially since I haven't changed my filter in a while. That would explain the dark vein, if his blood is infected. I'm expecting he will pass away while I am out helping my father move this morning, which makes me very sad. I will return that pleco immediately! They can take him off my hands! The only reason I got him was that the guy at the aquarium store told me I should have one for algae, but this is not worth it. I would rather scrape my tank than lose my favourite tank mates. They are my favourites, this tops off a great week including my bike being stolen. Poo.
