Need opinions

Hi all, at the moment i have a small 10 gallon tank with a baby african dwarf frog, two small angel fish, a dwarf pleco and an albino algea eater. I want to upgrade to a thirty gallon tall and add a plexiglass cave to it with a steep ledge that levels off about eleven inches from the top of the tank to a six inch ledge and extends about ten inches from the left side at the bottom. I was going to fill it to around four inches from the lid add a peacock eel and a small colony of cherry shrimp. i have checked out the ph and tempurature needs of them all and they are compatible in that manor. does this sound like a reasonable set up to you? and what if i were to add say 3 or 4 marbled hatchedfish? thanks in advance!!!!

Red Cherry Shrimp will just be an expensive meal in that tank.

agreed, you are putting a large bio load into the tank, yes you can use a thirty gallon tank but it will require weekly water changes, testing the water every week as well. Make sure you have a good filtering system on there.
I recently joined this website to learn about snakes but i have 10years with fish, I just recently got rid of my saltwater aquarium that i have had for 5 years now.
