Backstory: made a $100 offer on a 100gal. Offer got accepted. I was expecting only glass but it came with everything including fish... wasnt ready for fish and didn't plan on being ready for quite a while.(remodeling a house). Questions: what kind of tetras are these 2? And what is going on with the markings on the sailfin pleco? Is he ill? Yes I know I have some(obvious) compatibility issues been doing this for a long time, but it is what it is for now.
