My personal recommendation would be to let this clutch go and prepare for the next, but that's up to you. Like you I have done a TON of research into it and will at some point probably raise a clutch, but it certainly won't be one where I'm trying to order supplies while the eggs are already down. I would want to have my rotty culture going well before. I personally would create a post in the fish breeding forum and get help there, we have quite a few folks with a ton of experience.
