unless u tried to sell your aquarium when it was first introduced then its impossible
Once you've put the fish in your tank, you can't sell them.
Sell it.
you add the fish to the tank and it will just show up.
Its not possible to do that.
Well you could sell some things, you could have 299 gaia cash and than you go to the aquarium market and than go to specials.than buy one of those with gaia cash and then sell it in the market.
If you mean "how do you get 1000 gold in Gaia Online?", it's very easy. By posting, commenting, playing games and checking the AQuarium and Daily Chances, you should get about 1000 gold in one day.
A place where you can show yourself off and see what your avatar has. You can also edit it by showing of your pictures, aquarium, house and let them comment. (this answer is only for gaia online)
You cannot buy Gaia gold. There are no "safe shops". If you're found "buying gold" (which you're just going to get scammed out of cash), then you can be permabanned. You can, however, use your money to buy Gaia Cash directly from Gaia Online, and sell the items on the marketplace for gold.
Many aquarium specific and reptile/aquarium stores sell koi. Ask locally or do a search online to find a store near you.
