These hard to keep? Saw a video on these the other day, about 10 in tank. Any tips on keeping them?

Easy peasy but they don't have the longest lifespan. 2.5 gallon tank should meet your needs. No filter! They do not breathe via dissolved oxygen in the water and the water movement from the filter will "bug" them ,. Feed them Daphnia sp (water fleas) or large zooplankton, they need prey which does not float. Offer both cover in the water column and some floating cover. I will try to find some more info, it's been a while since I kept these. Which sp are you interested in?

Very cool insects
also think calm water and keep clean unchlorinated water for water changes

Gotta like aquatic insects
These are interesting and fun to watch doing the backstroke in pursuit of prey. ( live daphnia )
Little Scuba Divers lol
