Alright..they looked a lot like this, but without the colour cruely injected into them:

Anyway..now I hope all of that made sence, but my main point of this post is...how do you care for them? They are fresh water, if I am correct. How many gallon do they need each, and do they need to be in schools of their own kind? What other fish care compatable? What sort of heating do they need? Any information for care on these fish would be a great help. Thank you!
