I have had 3 Red-claw crabs in the past month die on me and I can't figure our why. I have a 20 gallon paludarium 1/2 water, 1/2 calcium sand with a large reptofilter in the corner that they can also climb on. It's brakish water and the tank never drops below 75 fahrenheit and it's had a glass lid on it so the tank is usually around 90% humidity. I feed them frozen blood worms and shrimp pellets.
What am I doing wrong, I feel awful that they keep dying... My tank is crabless right now and I don't want to get more until I can figure out why they keep dying....
