Large Backswimmers


5 in stock


Backswimmers live in freshwater creeks or ponds, etc. This listing is for larger backswimmers. These don’t make great tankmates with many other species because they are highly predators on things smaller than themselves. Consider the small backswimmers we offer. They are small and cheaper and do much better in communal tanks with others (offered through a separate listing).

Overnight shipping is highly recommended for these.

Please only choose overnight shipping as they are not likely to do well in slower shipping. Because they breathe air through their abdomens, water quality isn’t the same issue with them as it is with fish, etc. Provide a small bit of floating material in the tank for them to hold onto. These predators suck the juices from small prey. We also offer them pellet food (see link below) and sometimes drop frozen fruit flies in.

Current specimens are immatures or adults with indeterminate remaining lifespans. Adults have a lifespan of about 1 year, total. Do not release the adults into your backyard pond features, etc. They do not belong there.
