They're stunning little fish, I really like them. Tell me about it, if it wasn't for the fact it's a good 2 hour drive depending on how bad the motorways are I would pop down to visit the actual shop because they were also advertising quite a few wild Betta species including Betta Persephone which I'd be interested to see.
Getting my Betta Coccina to spawn has been pretty easy, it's just been getting them past the egg stage that's been a bit trickier. This is the 7th spawning I think, 5th with the same female and 2nd in the breeding tank.
