Do Black Tetras Blow Bubble Nest?

[Durbkat]

I have alot of black tetras in my long 20g (see sig) and since I've been treating them with maracyn for there fins I have noticed a bubble nest building up. Are my black tetras doing this and is that why one of my black tetras looks bloated?

I have 2 black tetras in my 10 gallon and i have noticed some bullets around the edges of the tank, perhaps they do?

No never mind I found out it was my common pleco that was blowing the bubbles. Because I saw him sticking his nose out of the water then he would blow alot of bubbles as he was going towards the ground.

as far as i know, no tetra is even capable of "blowing a bubble nest". their bodies are not designed for them to be able to take in any amount of air, much less release it into a bubble nest.

Well like I said above I said that it was my common pleco blowing the bubbles not the tetras.
