About black neon tetras...

[BigSteve]

◙ Since I was nearby anyway, I stopped into a local Petco to check
out what fish they had. I'm not too crazy about them in terms of customer service or
the quality of the fish they have, though I must say they are good about not overcrowding their tanks. Anyway, I was shocked to see the size of the black neon tetras there. The suckers were huge. I didn't know they got that big. It will make
me think twice about ever getting any unless I have a really big tank.

One of my LFS had some in a 125g. They were huge. I never knew they got that big .

Ya i agree. I saw some in a tank with 4-6'' CHERRY BARBS! They were all home bred and sold to the store

I went to a store today that had cardinals must have been at least 2" long each. though they were in like a 500G discus tank and weren't for sale.
