HCA: Hermit Crab Association

Hi I'm new to keeping hermit crabs I had been considering getting some for awhile and was doing research on them planning to build the perfect habitat for them before I got some but a family member got me one as a gift so I went from someday in the future to I need a setup now I'm just wondering if I'm doing this right I have a 36 gallon bowfront tank that has full spectrum lights a substrate is half aquarium sand and half bioactive mix currently there are two cholla pieces in there a betta log an aquarium plant that was sturdy enough to hold my gifted crab, declorinated fresh and salt water pools with sponge on the sides and stagum moss I currently have 5 crabs Bruno who was the one gifted to me he's about the size of a golf ball including his shell then I have four hermit crabs I got from a local store that are about a quarter to half of bruno's size I picked them up because I read that hermit crabs do better with friends I'm still trying to decide on names for them there are also some dairy cow isopods in the tank on the bioactive side temp is averaging 80 to 85f during the day and 75 to 80f at night humidity hovers right around 90

Hello!

It sounds like you're off to a great start. If you haven't done so already, you can check the care sheets. They have a lot of valuable information.

Do you know what brand or product your bioactive mix is?
