I've got a JBJ cubey that I've had for a while. I put sand in it, along with some live rock, and some palys, and have ignored it since then. I listed it a while ago for $80ish. Please drop me a PM if you are interested.
I have a 3G pico tank I'm selling for $30 comes with all original equipment. I have an ac70 that I used on it for an extra $20. Plus 2 led lights. Let me know I'm not on to often sorry.
