Red Veins On Face

[friendofish]

I recently bought what i believe to be Otos (Midget Suckermouths) and one of them has what looks like red veins down the sides of the face near the gills. Before i put him in with the other fish i would like to know if this is some sort of parasite or disease or something less sinister. I don't have a quarantine tank so an answer is needed quickly.

Cheers and sorry for the urgency

Red veins are caused by excess blood flowing to the area. It can be caused by a number of things but the most common is poor water quality followed by low oxygen levels. There is also a possibility it is a bacterial or fungal problem but that is less likely. If the fish is in a bag it is probably the first two option, poor water and low oxygen.
