Brown Tree Frogs Dying

I had 3 brown tree frogs 2 of them have died in the past 2 weeks. am I doing something wrong? The tank is clean and we feed them lost of crickets every 2 days because there are always some crickets that don't get eaten. The 2 Frogs that died mainly spent there time at the bottom and the other one at the top. Please help I don't want my last one dead. Thanks I appreciate it a lot if you would reply.
