Thanks to you both! I just read that article you provided, Steve, and it looks like the person was unsuccessful, as there was 100% fatality after 3 days.
However, I will take your advice and keep looking.
This afternoon I went shopping for refugium supplies and spent $200 on equipment, live rock, live sand, some Chaetomorpha Algae, also known as Spaghetti Algae; added a lot of water and sand from my other tank, etc. It's cycling now, but don't think it'll be ready for my fry. We'll see - I don't know what else to do or even when my blennie will be ready to lay her eggs. So if I don't find any answers, I'll be winging it.
If anyone is interested, I could keep you posted if anything happens.
