I am going to set up a 29 gallon tank, but I want to raise Endlers in it too. So I want to use an underground filter and a back filter. I have my gravel but since I want to raise some nice lower light plants, what substrates do I need to put down. This is a first for me. I always , in the past just put gravel and prayed something would live. Now I really want a nice looking planted Endler tank. Could ya'll give me some suggestions, and as reasonable as possible. Thanks, in advance, this site is the Greatest for helping out.. I am so lucky to be a part of it, and hopefully I can help someone out too someday. Any one want some nice Mystery snails, or is that a no no??? these are purple. And soon I will have lots of very nice Endlers.
