Thanks oddball. I have found some conflicting info about size 8inch or 15 thats massive diff and some web sites say fins turn red as they mature. Does anyone have these in there aquarium or past experience kept them to help out with size or fins turning red pics would be nice if its not too much hastle. thanks
