Feeding & Nutrition

Moss arrived in a padded envelope from a breeder three towns over, a six-inch smudge of pink with gills like little fans, and I set him up in a ten-gallon tank with the kind of focus people usually reserve for a new phone. I'd read the care sheets, cycled the water for a month, bought the sand they said was safe, the sponge filter with the soft flow, the dim LED that wouldn't stress him. The breeder said he ate bloodworms. She did not say he ate them only if they were moving, which is the sort of detail you learn the hard way at midnight when you are holding a turkey baster full of dead worms he has ignored for six days and starting to wonder if you killed the thing in transit.

I had been dropping the thawed bloodworms in a little clump near his front feet. He'd swim over, look at them the way you look at a chair someone left in the hallway, and drift away to the far corner, where he'd sit like a small pink statue contemplating a life he hadn't chosen. I thought he was stressed from shipping. Then I thought the worms were bad. Then I thought the water was wrong, tested it twice, panicked about ammonia that wasn't there. On the seventh day I poked one worm with the tip of a feeding tong and it twitched. Moss's head snapped around like he'd been waiting for that exact motion his whole life, and the worm was gone before I'd lowered the tong an inch.

That was the whole lesson, and it took me a week to learn it. Axolotls are sight and vibration hunters. In the wild they wait for something that moves and then they strike, a slow-motion lunge that looks lazy until you realize how precise it is, how the mouth opens at just the right moment to pull the prey in with a suction you can feel through the glass if you hold your hand near. Still food reads as nothing, as part of the gravel, as background noise in a world they experience mostly through motion. A wiggling worm reads as lunch. The difference is not the food. It's the motion, and until I gave him that motion he was a well-kept, well-loved, starving animal.

I switched to feeding with long tweezers, holding the worm just above his face and giving it a small jitter every few seconds, the way you'd dangle a string for a kitten if the kitten lived underwater and had no legs. He eats now like it's his job, head rising off the sand, body tilting up, mouth opening with that soft vacuum that pulls the worm in whole. I've watched him refuse a worm that drifted down motionless and then take the identical worm the second I nudged it. He is not picky. He is wired to a sensor I didn't know existed, and once I learned where the switch was, feeding stopped being a nightly dread.

What this taught me about the rest of them

After Moss I started looking at all my animals through the same lens, and the pattern held in ways that embarrassed me. The betta flares at movement and ignores the still pellet. The cat pounces on the toy that darts, not the one that sits on the floor waiting. The dog alerts to sound first and meaning second, his ears catching the rustle before his brain catches up to the cause. We talk about pets as if they have preferences the way we do, little personalities with opinions, but half the time what looks like a preference is just a sense that only fires under certain conditions. Moss doesn't hate bloodworms. He simply cannot register them until they move, and the failure was mine for not moving them.

I keep a small jar of live blackworms now for the days he turns up his nose at the frozen kind, which is rare but real, usually after a water change when everything feels unfamiliar to him and the world briefly stops making sense. Live food wiggles on its own, and on those off days it's the only thing he'll take. It costs more and it's a little gross to keep in the fridge next to the butter, and my partner gives me a look every time the jar comes out, but watching a creature eat with appetite after a week of worry is its own small relief, and I've stopped resenting the extra step that keeps him alive and well.

The tank sits by my desk now, a quiet pink neighbor to my working hours. When I'm stuck on something I watch him hunt, and it's a decent reminder that most problems of appetite, in animals and maybe in people, are really problems of attention. Give the thing a reason to notice, a flicker of motion in the stillness, and the rest tends to follow. Moss taught me that for the price of a week of worry and a jar of worms, and I'd rather have learned it from him than from a more expensive mistake.
