Down Breeding
Behaviour To start was 1M and 1F with other male trying to tempt other 2 F. After 30min no success, joined other male courting gravid female. Males tend to lose track of female a lot and end up chasing each other till they find her again. Other 2 females not interested, 1 doesn't look chunky enough, and just forage around tank. Gravid female seeming to prefer original male over 2nd late comer. Spawning lasted approximately 1-2 hours with 30 eggs deposited on front glass, no others found around tank. They took a break for 2 hours, second female followed by 2 males deposited 70 eggs again on front glass no others found in tank. First 30 were removed from tank to breeder box with 2 drops methyl blue after 1 hour no activity. Last 70 eggs were removed and added to breeder box. Spawned asgain 3 weeks later after another WC, without nitrites being so high, this time all 3 females spawned a total of 130 eggs.

Fry and juvenile feeding As I always seem to kill off my microworm cultures, I've been feeding them the repashy soilent green but not in gel form. Fed once a day just under 1/4 teaspoon of straight powder mixed with tank water, squirted gently into breeder via small pipette. It doesn't foul the water and allows them to forage all day. I use a small pipette to suction off the leftover before the next feeding, only problem is it does collect in the sponge over the out feed from the breeder but a quick squeezing in the main tank clears it. Plus the fish in the main tank will scavenge it.
