Bloodfin Tetra can go mighty cool, 64 to 82 degrees F and are very hardy. There colors do pale in lower temps. They can live to be 10 years. But if your
Goldfish is a long tail variety, some Bloodfins can be a bit nippy, I hear. That hasn't been my experience, though.
That's fantastic that you got her fish set up in a swank crib! Way cool!
BUT (I'm sorry, there is a "BUT")... Do be careful mixing other fish with
Goldfish. Really, I don't recommend it.
Goldfish are waste factories! Its crazy how much waste they produce, even relative to size! And with how big they can get, it gets even more crazy. What kind of
Goldfish is it? Because, if she won it at a fair, its probably the common variety. And if that's the case, and to be honest... I don't think that you'd have room for any other fish in a 29g tank. In fact, your
Goldfish will out grow your tank. It could end up a foot long!
I'm sorry to be the bearer of bad news...
