here is my question. I am interested in getting 2-3 for my tank... no more than 3 as I am close to my limit on fish I feel (unless someone wants 3 very fat gold barbs that they can have for shipping cost only as long as they tell me how to ship them!) I just want to be sure they cant eat my Neons... from what I have found they get to about 2" maybe 2.5" MAX. Is this true and would 2-3 be ok on my 20 gallon??? I also am going to be planted within the week and want to be sure they wont eat all my plants lol
They'll be fine. Won't eat your fish, they eat algae. In my tank, they completely ignore the other fish and vice versa. You also don't have to worry about your plants, in fact, they can help by rasping algae off the leaves.
