Want to start keeping diving beetles

[30RatsInATrenchcoat]

Hi! I’ve never kept insects before but would love to keep giant diving beetles. Already checked out bugs in cyberspace and have learned about a few species and their diets. How big of a tank should I have? I have a 5 gallon already. I’ve kept aquariums for several years and currently have a pet musk turtle.
Any resources or species you recommend?
Thanks, it’s my first post

My fiancé got the wonderous opportunity of unboxing these little guys while I’m away. They’ve already explored, eaten, and even began to mate. As a diehard “I hate it when animals don’t live a long time” kind of person, these little beetles have captured my love and I cannot wait to try our hand...

Try searching for scientific names, at a minimum the genus you are interested in.

Some species I’m interested in are
- Lethocerus americanus
- Cybister lateralimarginalis

I’m also interested in a aquatic beetle community tank because that sounds really interesting and like it’d be more fun to watch. Sorry if I got any of the names wrong, I’m used to mammals and fish.

I've kept a few larger predaceous diving beetle species before - incredibly easy to keep. I had them in a small tank with floating plants and some driftwood. I tong fed them superworms and crickets, they were very eager eaters.
