Do Any Vampire Crabs Not Need Burrowing Space
No. Every vampire crab line in the hobby needs a land floor of soft, damp substrate it can dig into. It also needs enough cover for each crab to get out of sight, and that includes the ones that climb…
Vampire Crab Care
Every guide we have written on keeping vampire crabs (Geosesarma), the small semi-terrestrial crabs that live on land and go into the water to feed and to molt. The guides cover the paludarium build, climate, food, group size, telling males from females and breeding in fresh water. New to vampire crabs? Start with vampire crab care. Building the enclosure? Vampire crab tank setup walks through it step by step.
Can Vampire Crabs Live With Shrimp?
Yes. In most tanks vampire crabs and dwarf shrimp live together fine: the crabs chase shrimp but catch few, and Neocaridina keep breeding in the water section. Losses pile up when a handful of shrimp go into a small, thinly…
Can Ghost Shrimp Live With Vampire Crabs in a 20-Gallon Tank
Yes, adult ghost shrimp usually work with vampire crabs in a 20-gallon paludarium. A grown ghost shrimp is several times longer than a vampire crab’s shell is wide. Both animals are happy at the temperature you’d keep the crabs at,…
Do Vampire Crabs Breed More in a Smaller Tank
No. A smaller tank won’t push a vampire crab female into a bigger clutch, so it won’t give you more babies. What changes how many young you raise is cover and separation, because adults eat the young they catch. How…
Too Many Vampire Crab Babies? What to Do With Surplus Crablets
Move the vampire crab babies you want to raise into a separate grow-out tub, rehome the extras through other keepers or a local fish store once they’ve colored up, and keep males and females apart so the broods stop. Whatever…
Does Inbreeding Affect Vampire Crabs? How It Builds and How to Avoid It
Yes, inbreeding can affect vampire crabs, though it creeps in over generations and doesn’t wreck a colony overnight. No study has measured it in vampire crabs themselves, but in a small freshwater shrimp a single generation of brother-sister mating already…
Can You Keep a Male and Female Vampire Crab Without Them Breeding
No, a male and female vampire crab kept together can’t be reliably stopped from breeding. If you keep an adult pair together, plan for crablets, because these crabs need nothing more than a freshwater paludarium to raise young, and there’s…
How Long Do Baby Vampire Crabs Take to Color Up
Baby vampire crabs take about 6-12 months to reach full adult color. They start out clear, brown or dark. The first color often shows at the claw tips from about 1.5 months, and the rest creeps in slowly over many…
Should You Separate a Male Vampire Crab That Keeps Attacking a Female?
Yes. If a male vampire crab keeps chasing the same female out of cover, or she’s losing legs or claws, move him to a tank of his own. A single scuffle is normal in a group, but repeated attacks on…
Should You Move Adult Vampire Crabs After the Babies Appear
Yes. If you want the babies to survive in any number, move every adult vampire crab into a second, fully set-up paludarium and leave the crablets where they hatched. Adult vampire crabs eat the crablets they catch, so splitting the…
How to Keep a Vampire Crab Tank Humid: Lid, Moss, Misting and Mold
Keep a vampire crab tank humid by closing the lid, keeping the moss and land substrate damp, and misting about once a day, more often while new moss is settling in. You don’t need to hit a set number. What…
How Land Cycling Works in a Vampire Crab Paludarium
Land cycling in a vampire crab paludarium is really two jobs running on two clocks. The water section has to grow the bacteria that turn waste into nitrate, the same way an aquarium does. The land has to settle until…
