I put a black cap basslet in my 13.5 gallon tank 6 weeks ago. I’ve been feeding it nano reef frenzy with forceps 2x daily and it has always rushed to grab the food. The last two days it’s been staying close to it’s cave and comes out to feed, but only approaches then goes kind of still and opens its mouth really wide without taking the food.
Additional tank context: Over the course of the past two months, I’ve incrementally added a handful of inverts (various snails and a blue leg hermit - I also have a sizeable spaghetti worm that’s take up residence), a young common clown, and starting about two weeks ago a couple of mushroom coral, a leather toadstool, and three zoa frags. Water parameters are still stabilizing, but nothing too alarming. The clown and the basslet seem to be coexisting just fine - no observed aggression even during feeding.
I don’t see spots that would indicate ich but I know there’s an entire host of crap that can cause behavior changes in fish. I dipped and rinsed all of my corals per the insert. The clown isn’t acting weird. No new inverts for the past two weeks. But everything is so new - it could be anything.
Anyone have experience the wide open mouth “screaming at me” thing?
