thing?â
Before Ms. Sanchez could answer, Hammer, the club-wielding attack shrimp, came out of his burrow. The creature stood up on his middle legs and rotated his freaky half-blue, half-pink eyeballs around. The stomatopod then crawled to the tankâs bubble-wrapped front wall and struck with such ferocity that Tristan leapt backwards, thinking the glass would shatter. Before disappearing back into his sandy burrow, Hammer took a moment to also smack the miniature fighting dummy over the head.
âThereâs your answer. I donât think Hammer likes us watching him eat, and besides, he has a serious anger management issue. Itâs why heâs here. The residents of the reef where he lives were sick of him destroying the neighborhood and attacking other creatures. They asked if we could do something. It was sort of an undersea intervention. We sent a team in to work with his neighbors and lure him out of his burrow. Theyconvinced Hammer to come here for help. We need to figure out why heâs so mad and find other ways for him to deal with his anger. But so far, the only thing thatâs happened is that heâs destroyed three of those fighting dummies and cracked two aquariums. Weâre hoping heâll take a shine to someone soon and open up about his problems.â
âHey,â Tristan said. âMaybe Hugh can help. Heâs pretty good with the communication thing.â
âMaybe,â Ms. Sanchez replied. âI really donât want to lose any more tanks.â She moved on to another aquarium nearby. It was larger than the first and half-filled with rubble, some corals, and a cluster of sea anemones that resembled flat, multicolored flowers.
Tristan peered into the tank. He didnât see anything all that unusual. He recognized a cute, two-inch-long pufferfish. It was brown with white, crisscrossing lines, had a skinny little snout, and had a barely-there tail. There was also a tiny, bright yellow, coin-shaped fish and a few skinny ones with stripes like heâd seen in the stream earlier.
âSee the fish in the corner with the big black eyes? The silvery one with the pinkish-red, horizontal stripes?â
âYeah, that one.â Tristan pointed to a fish about three inches long.
âThatâs a juvenile squirrelfish. Theyâre nocturnal. They hide in the reef during the day and then come out at night to hunt. Thatâs why theyâve got those big eyesâfor night vision.â
âBut itâs daytime, and itâs out swimming around.â
Ms. Sanchez nodded. âExactly. Thatâs the problem. Sandy here is afraid of the dark. Weâve been putting a nightlight in the tank after dark with some food to entice her out. Weâre trying to get her to feed regularly at night and then wean her off the light.â
They moved on to the condo complex of aquariums that was Old Jackâs homeâthe campâs resident elderly octopus. Like last year, there was a collection of pickle jars, some rocks, seaweed, and a variety of plastic play toys in the tanks. A Rubikâs Cube sat in one aquarium. It looked dingy. It was covered with a thin film of algae, as if it hadnât been played with in a long time.
âIs he still in there?â Tristan asked, thinking that Hugh would be really bummed if Old Jack had died.
âOh, heâs in there. But heâs been coming out of his hiding spots less and less often, and heâs moving more slowly. Weâre not sure how much time Old Jack has left.â
After searching unsuccessfully for the elderly octopus, they moved on. Ms. Sanchez showed Tristan a spiny lobster whose long front spines had been torn off by a careless diver. The lobster had been fitted with prosthetic spines and was walking tentatively around the tank feeling things, like a blind person using a cane for the first time.
Ms. Sanchez looked at her watch. âLook at the time. Youâd better get over
