my size of aquarium is 2.5 by 1.5.
There is 10 gold fish in there 7 little big and 3 little small. there are total 12 fishes in there.
Is it beautifull
upload pictures of your tank.
if this is a 2.5 foot by 1.5 foot then its grossly overstocked with that many fish.
What size in cm's or inches are these fish ?
