Liquifry at the very start - you can buy it online or at your LFS.
Then I cultured microworms. These are really cool! Again, easy to buy - https://www.amazon.co.uk/Proximus_N1-Microworms-culture-Microworm-nematode/dp/B00CQR2SAK
I made some warm porridge, put it into an old takeaway food container, and sprinkled the microworm culture on top. Keep it moist (I stretched clingfilm over the top and periodically dropped water onto the culture.
Within a day or so you’ll see shimmery, tiny creatures, so small you can’t see individuals, starting to climb up the edges of your container. They’ll look like a fungus, but they’re the microworms!
With a damp finger, just wipe a few off the edges of your container and swirl into your fry. They’ll suddenly “peck” and dart for the microworms - it’s lovely to watch!
At the same time, order baby brine shrimp eggs - I’ve just used https/www.amazon.co.uk/Shrimp-Artemia-Hatching-Individual-Sachets/dp/B0968B6LMV/ref=sxts_rp_s_sp_1_0?content-id=amzn1.sym.9b19a5b4-8367-4c22-a2e8-308de46e7871:amzn1.sym.9b19a5b4-8367-4c22-a2e8-308de46e7871&crid=3JGU7EQWBOH97&cv_ct_cx=brine+shrimp+eggs&keywords=brine+shrimp+eggs&pd_rd_i=B0968B6LMV&pd_rd_r=fb98d246-30e7-463c-b15f-34142390c2fb&pd_rd_w=BI1u1&pd_rd_wg=7D5zU&pf_rd_p=9b19a5b4-8367-4c22-a2e8-308de46e7871&pf_rd_r=1PJE3XH3R9D51WCCZ0TV&qid=1679722230&sbo=RZvfv//HxDF+O5021pAnSA==&sprefix=brine+shrimp,aps,153&sr=1-1-1ccd8dd6-22b2-400b-bddc-4df1f1459235
And they’ve hatched well. Again, a takeaway food container, salted, warm water (no porridge this time!) and sprinkle some eggs in. The ones in the link I give here also contain salt but you can buy just eggs on their own and use table salt.
These will hatch in 24 hours. When you want to feed the fry, put your phone light at one end of the container (the baby shrimp are attracted to light) and, using a turkey blaster, suck a few up. Try to avoid sucking up the egg casings; it’s an easy job.
Then plop them into the water with your fry!
Siphoning up the uneaten food was a chore, but actually creating the food for them was fun ☺️
