Ok in my tank I have 10 goldfish that have been there about a year and doing wonderfully despite being a little crowded...(Some being sold to good friends soon). Well I used to work for PetsMart and some dude comes in with a sammich bag full of itty bitty platies! He wanted us to feed them to our oscars. I told him no and took them home myself. Well I held little hope for them in with my goldfish, even though their water is heated to about 77 degrees, they were just so small. Well...they are near full size now and doing great!! They are very pretty, red with black on their sides, almost irridencent. Now I need to find them homes...lol I am a semi-aggressive fish lover with a soft spot for communities.,,,
