I havn't kept striated or sargassam angler. I did however keep a bright yellow wart skin angler. They truly are amazing fish to keep, but be wary, as I have seen anglers take prey larger than themselves. I could only ever convince my angler fish to take live food, but it was worth it! really cool fish. Three things to be carefull of. One is overfeeding, as this can kill them quickly. Another is fungus, as it can be hard to spot on anglers till too late. The third is the heat. They really cant seem to take water above 30 degrees (C). But otherwie they are a kick ass fish and I would recommend them to anyone. One other thing, if you get one that only eats live food, keep it in a small-ish area (if the angler is small, a breeder trap will do), as they wont take food till its pretty much touching their nose (usually).
