A pair of my rams laid eggs earlier this week. I took an air hose and sucked the eggs out into a 2.5g tank I have laying around. I added some anti-fungal (I used kanaplex, but it's probably not available in the UK p I have heard hydrogen peroxide works too).
I put a strong airstone and heater to keep the water at the same temp as the parent's tank. They hatched into wigglers on Thursday. This morning, they started swimming free. I started feeding them liquifry today. You can see them eat it. The slide backward a bit, and lunge at the dot of food they are eating. Funny stuff.
I put some duckweed in the tank and put a desk lamp over the top to hopefully help keep ammonia/nitrites/nitrates down, since there is no filter on the tank.
I started cleaning the bottom of the 2.5G tank by using my trusty air hose as a mini vac, sucking all the gunk off the bottom into a bucket, careful not to get any fry.
I'll be doing 10% daily water change/bottom vacs till I move them to another tank that is cycled - when they are big enough not to get sucked into filter intakes.
I will feed them the liquifry for probably about 3 more days, then switch over to hikari first bites. I'll feed them that for a bit, and once I think they're big enough, I will start feeding them BBS.
I have heard that rams do not have a lot of spawns in their lifespan, so sometimes do not become competent parents, and it is advisable to manually raise some of their spawn, if you want to be sure to end up with new rams.
