got redcap veiltail koi angels. had got just 2, and luckily they turned out to be a pair. they laid eggs on an amazon leaf. i have separated the leaf and kept it in a separate tank(bare bottomed). now they are hatching. Little threads sticking out of the eggs and wriggling. have added methyl blue to the water. what do I do next? I have access to only flakes, tubifex and blood worm. no brine shrimps, or infusoria. Please help
