Title says it all. I recently purchased 16 of these little buggers for my tank and so far they have been great fish. Entertaining, gorgeous, and easy to care for. Anyone else with experience with these?
They're vicious eaters and will strike at anything that hits the water. They're fun to watch. I heard that the gold color is caused by a parasite and that tank-bred ones turn out to be silver because the parasite needs some other host before infecting the fish that isn't found in our tanks.
I have 7 gold tetras! I bought them from a tiny shop in Chinatown; I'd never seen that breed of tetra before, so I bought them all. So far, they have been great--very peaceful, none have died. They are bigger than neons, but not by much, and have thick bodies like neons. Mine are not especially active compared to some of my other tetra species. They share the tank with cardinals, rummynose, zebra danios, harlequin rasboras, and a pearl gourami. I recommend them!
Cardinal, I have also read that the gold color is caused by a parasite. I have no idea whether it's true. Mine have remained gold.
I have two Penguin Tetras who are magnificent and I'm dying to get my hands on at least 5 more to make a proper school, but I can't find any. The two I bought were the last two in the tank at the LFS.
