I am planning a future build that will probably be a couple of years from now before it happens.
I have an acrylic guy who can build anything I can dream up of, so I plan to start gathering all of the equipment including the tank soon.
Here is what I want to accomplish...
I want a FO
tank to house a cat shark, snowflake eel, & a porcupine puffer.
The first question is compatibility, whats your opinion? I plan to add them all around the same time while they are all small, yet big enough not to become eel food.
Next is tank size... I haven't determined this yet, I was thinking of a square tank with less height and more depth, I think this would allow for a smaller water volume while still giving the fish & shark the room they need. I am thinking a 200-250g would probably be sufficient. Thoughts & input welcome, this is just an initial guess, I feel it would be better for the shark than a standard 200+ as this would be more square footage.
I would want minimal rock in the tank and was thinking of a center overflow with diy rock built around it like a centered column with lots of eel hiding places. This way the shark will have lots of surface area to roam. Also this will allow me to place the tank in the center of a room or as a divider should i move it in the future.
Probably a 4" fine sand bed. I already have a 50g sump built and an AquaC EV-240, and plan to build a large algae turf scrubber as the main filtration to supplement the fact that there will be little LR
in the system. Considering the Tunze Wavebox for water movement.
This is just the beginning thoughts, I need to do lots of research and am definitely taking my time on this, want to plan everything perfectly before I buy anything.
