Hello all. This isn't a question just an observation in my tank. I have a 20 gallon long VERY heavily planted tank. So heavily planted that you couldn't see the substrate. There's a link at the bottom of my tank for reference (the corys were only out in that video because I dropped some pellets in) Ever since the dwarf sag and s.repens took over the entire substrate my corys stayed in one small area behind the drift wood were sand was still exposed. Yesterday morning I made the sudden decision to rip out all of my s.repens and re-organize my dwarf sag to leave the front of the tanks substrate area plant free so the corys could have an area to sift through the sand. The s.repens became so thick it was just a food trap and snail breeding haven anyways. Ever since the change the corys have been out and about non stop sifting through the sand and zipping around instead of staying in their previous tiny sand patch. So a note to all planted tank with cory cat owners....be sure to leave them plenty of space to dig around in the sand instead of carpeting you're entire tank with plants. It's awesome to see my cory's behaving normally and digging around again! Here's the link to what my tank used to look like and below is a pic of what it is now (still a bit cloudy from ripping out heaps of s.repens) let me know what you think!
