I wasn't really referring to the sand bed size, and keeping them alive just with that. I was going on the assumption that they will take prepared foods eventually
. I just meant that a 20g could be small for fish that need constant feedings (water quality issues), but now you mention the aquaC remora, I think you'll be fine...just keep up the water changes too. Good luck with them, if you decide to go for it :thumbsup: PS - You might want to do a search, but I believe black worms are FW, and don't carry proper nutritional value for marine fish long term.
