I got two Tetras last week. A Black Skirt Tetra and a Red Eye Tetra. I have had a Platy for a while now. The problem is, for the first few days, all fish ate the flakes I gave them, but now the Black Skirt Tetra has stopped eating. I have been watching him for three days and he hasn't eaten at all. I have tried dried blood worms, Goldfish pellets, Goldfish flakes and the usual tropical flakes. Other fish ate everything (except pellets because they couldn't swallow, but they kept nibbling) but not this guy.

The tank looks fine and I have been changing 25% water every other day. I also change 50-75% water every week. Yesterday I changed 75% water hoping to make the BST feel better and help him eat. But that didn't work.

I am running out of ideas. He is the biggest fish in the tank so its hard to imagine him being bullied by other fish but he does not come up for food and when the flakes are floating in front of him, he does not seem interested.
 
OMG I did not know Tetra needed to be in a school. Petsmart person did not say this either. This is a 15 gallon tank. I don't think I can get 3 more of each. At 9 fish total, that would surely crowd the tank.
 
platies are not tetras, but they appreciate the company of their own species.

you will need six of each individual species. that means you will need six red eye tetra sna dsix black skirt tetras. your best bet here would be to take back either the black skirt or the red eye and then get 5 more of whatever you kept.
