So my 30 gallon tank, with large gravel stones I don't like, is going to be changed a lot. Quite a lot. Currently the tank has 3 Corydoras Paleatus and 3 Corydoras Metea as well as several snails and a few ghost shrimp I never see. I plan on removing the gravel and adding about an inch - inch and a half of sand. I have a whisper filter that I plan on covering with filter floss and pantyhose to protect it from the sand. I'll most likely use pool filter sand, mostly because it looks great and the Cories love it. Plant-wise, I have a massive Water Sprite plant I want to sell somewhere, a couple of apontegen plants I got from bulbs, java moss and 4 sprigs of red wendhI that won't grow. I plan on buying some dwarf sag. Fish wise, I'm getting a breeding pair of honey gouramis and 6 cherries, as well as maybe getting 4-5 pygmy corydoras. Thoughts?
