We won’t get species specific, as they can be difficult for some to ID properly and the care is relatively the same from species to species. That being said, the most common species encountered in the aquarium trade is I. didactylus. Others less commonly seen, yet found are the filamentosus, sinensis, caledonicus and the japonicus.
Coloration is variable, ranging from mottled, muted grays and browns to gorgeous pinks, reds, and oranges. Their eyes resemble two BBs sitting atop the fish’s rather flat head, and finally, an upturned snout that is perfect for ambushing passing prey. As with the other stingfishes, their first two pectoral rays have evolved into fingerlike appendages known as dactyls. Although they won’t walk around on them like the Chorydactyline stingfishes, they do indeed use them to lunge at their prey from beneath the sandbed.
In the aquarium, we have found this species to be fairly easy to keep. Don’t expect the Inimicus to be one of those out and about fish, as much of their time is spent buried up to their eyes in the substrate with one or two dorsal rays showing as well as their dactyls. Inimicus tend to be strong feeders, keep to themselves (unless their tankmates are bite-size), and like most scorps, are fairly disease resistant. Our specimens have all been relatively easy to feed and wean, although we have heard of instances where the opposite was true, and also of a couple of fish that refused food altogether.
