Hi all. I didn't want to go the traditional "sloping sand"-route in creating a habitat for my mudskippers. To start with, I had three Periophthalmodon septemradiatus males. This is not the most aggressive nor largest species of 'skippers, but it still wants to form and defend a small territory. What I wanted was to create a habitat with multiple spots where the fish can hide from each other's sight. I started with an old 140 gallon sump tank: I disassembled the sump to replace the old, scratched front glass with a new one and painted the trims: For hardscape I wanted to make a DIY root system with multiple little shallow pools and an inbuilt plumming to circulate water in the pools. A sketch: Platforms and volume of the scape: Roots bent of pvc and added volume with foam: A bit of shaping with a knife: A stage after a few layers: Hardscape pretty much finished: Glued in and the first test was very succesfull. All the pools were filled up with just one pump feeding the plumming system in the scape: The mudskippers are using the whole scape and seem happy with it: FTS, early stages: BOOOOO! The tank is still maturing. Water is kept at 1.002-1.003. I'm trying to find plants that would co-operate with me, but haven' had too much luck yet. There, thanks for looking!
