I'm finally setting up a mountain scape in my 35 hex, planned as a shrimp tank. Not sure what type, I've only kept amanos so far. If there's any fish it's going to be a school of ottos, corydora hastatus, or some tiny boraras sp. I'll figure that out after I get it going. Right now there's 4 male floppy tails honeymooning in the tank.
I'm running a Current USA Subcurrent internal filter. It's the surface skimmer that looks like an overflow box. I really like the dual loc-line outlets and the flow rate is perfect for this tank. Good movement without laying down the plants. No heater yet, room temp is holding the water between 70-75. I will add one just to keep things more consistent.
The lighting is what could be a disaster.. I have a 150w HQI light over it with no co2. The plan is to keep the light high off the water to start, use a short photoperiod, and daily dosing of Excel to try and keep the algae at bay. If that doesn't work I might just have to get some co2 equipment.
The other concern is the rock work. They are just sitting on substrate, no rocks underneath to support them and the slopes. I'm hoping the roots hold it together. The rocks are placed pretty safe in my opinion, no crazy angles or balancing acts. Let's just hope they don't fall and shatter the side!
