I've tried putting a couple of different pics facing into the tank of percs hosting bubble tips, but no luck. Not sure what else to try?
I've read that sometimes they dive right in, sometimes it takes hours/days/weeks/month, and something it just doesn't happen. I'd planned on just leaving it a few months, and if nothing happened either swapping out my clowns, or getting a porcelain crab (more for interest, and it's supposed to make for a healthier nem). However, I'm struggling to get food into the nem, so need to do something.
I tried feeding the shrimp a bit of fish each to distract them, but they tended to lose it to a fish or another shrimp and then head straight to the nem. I tried using an algae clip to hold a bit of fish, which worked well, but after several fish and one shrimp had a go, it vanished pretty quickly.
