Lawnmower blennies aren't always the best eaters of prepared foods. My current one didn't eat frozen for several months (I wanna say 6, but can't remember).I have a lawnmower blenny, i’am having a difficult time getting him fed. There is a limited amount of algae in my tank, I have tried algae wafers, brine shrimp, nori. Any suggestions ?
You might try something live, like live brine or if your fish store happens to have blackworms or white worms. On the nori, I usually tell people to try a rubberband on a rock rather than a clip. That sometimes works.
It can be a challenge. They are also infamous jumpers.
