Those are beautiful looking fish Robby!
I have been feeding the adults the bbs every time I feed the fry. If I didn't I'd end up throwing half the bbs away anyway and it's perfect for the Threadfins who haven't been doing very well recently
With the bbs, once they've hatched do I need to continue the aeration (I know I have to use them within a day or two)? I've bought some food for the brine shrimp which I'm hoping will prevent the first hatched from dying and polluting the water while I hatch the next batch though I know the yolk sac will be gone and therefore the nutritient value will be far less.
I think the deaths may have been from the water as the hatching container was floating in the fry tank and as I used an anti-fungal treatment in the water I didn't aerate it. The fry hatched about 2 minutes before I ws going to leave to go to work so I didn't transfer them to the fry tank until about 4 hours after hatching (the fry tank being a breeding net within the original fry tank contining the month old fry so temp fluctuation is out of the equation). However, they are constantly spawning, I can't seem to stop them, so even with constant feeds of frozen food (daphnia, artemia, bloodworm) it must be taking it out of them. I think the only way to stop them spawning is going to be to drastically reduce the photoperiod andtry to give them chance to build themselves back up again! Hopefully the bbs will help with this.
Thanks again for all the advice, it's much appreciated!
