No, Tetra, yeah they do swim up and down, I see them scavenging on the bottom a lot also, mainly on the bottom.
I have mum and dad out of that tank now as I have put the half grown babies in there, I seem to be getting mostly female Betta.
The Tetra were interested in the smaller fish, no problems yet with them nipping, the girls turn on them in a pack sort of surrounding any aggressor.
I have strange fish, very strange.
I don't think I would add any more varieties of fish since mum and dad went to work again laying more eggs when I put them in a smaller tank, 4ft tank for 2 Betta was a tad wasteful Lol the babies love it.
