I have one in my 75g he’s been in there about a year, I added a fuzzy dwarf lionfish about 3-4 months ago I saw him so lil I totally forgot I had a Pom Pom, I have seen my fuzzy try him a few times but he was just a tad too big for his mouth and they have pretty good grip the lionfish suction is not strong enough to un grip him or my emerald which he often looks at but kinda gave up on but I’m sure eventually he will be a snack.
