Yeah I had a pair of burdigala in a 7 gallon tank. They bred a couple times. First time I moved the film canister and young fry over into a grow-out. Got over 20 of them. Then I found more fry in the tank so I decided to remove as many as I could, which totalled about 40. I noticed a couple of stragglers but wasn't really fussed about catching them.
Now everyone is bigger it turns out that there are at least 20 juveniles/fry in the tank still. There are probably more, but haven't done an official count.
The only good thing with these species is that when the juveniles start to colour up the parents usually stop spawning. This gives me at least some breathing space then between growing-out spawns. Plus they have nowhere near as many fry as the splendens complex bubblenesters.
