P L A T I E S!!!!! they are NICE but some are LFS raised and scared of people, they come up and kiss your finger when you tough it to the water, swordtails are cool but you should get a baby one b/c the fullgrown ones are grumpy and food hogs but thats probably b/c the lfs had them in an 8 gal with over 30 fish and they fed the fish 1 small inch of food.... maybe thats why their kois are dying...
