Black piranhas are fairly easy to get online... And is see the snakehead is out lol... There are few advantages to living in the UK but owning snakeheads is a big one.
I know I'm probably going to get a lot of hate for this, but I say get a divider and have two bettas and two tetra (or similar) communities to go with them.
Example: each side would have 1 betta, maybe two groups of tetras and either cory cats or kuhlli loaches as bottom feeders, but the bettas would be the main features aka "pets".
They have tons of personality as well.
Post Script: No hate please, I like bettas and would love to see more people keeping them in decent sized tanks. Again, no hate please.![]()
Tell that to the governmentWhat about wimple piranhas? They aren't really piranhas
