How big is your tank? How long has it been running? What else is in the tank with your tetras?

Welcome to Fish Lore!

Is your tank fully cycled? Is it a 20 gallon long or tall tank?

I'd get more cardinals and red eyes, make it 8 of each. You don't really have enough room to add another full school of tetras.

I got 5 Pristella Tetras a couple of months ago....they are really fun fish, and all the tetras seem to sort of hang together. You could do with 3 or 4 just fine. I have neons, cardinals, rainbows, and pristella tetras. Only the Rainbows stay apart from the others.

I agree that you do not have room in a 20 gallon for another type of tetra. The ones you already have school in the same area of the tank and another type would really overcrowd that space. I would round out the school of cardinals to 7 and call it a day.

What do you folks think about something like 3 cories in this tank?
