Could we give them a more interesting collective name than a "school"?
Since they resemble flat stones, how about a "paving" or "cobble" of gray flatfish?
Well, they are fish...
But if you insist, I suppose cobble appeals.
Here's the next one...
Cobra Trout: Int Animal; AL CN; MV 1, Sw 12; HD 2 hp; #AT 1; Dmg 1; THAC0 20; SA poison; SZ T (2’ long); ML 5; XP 35.
The cobra trout, which lives in the Deeping Stream, is one of the few fresh water fish with a poisonous bite. Extremely territorial, the cobra trout lunges at any creature that comes within a few feet. This fish can exist on dry land for as long as an hour, using tiny fins to haul itself along the ground. Fortunately, its bright silver scales make it easy to recognize and avoid.
