The tank will most likely house 3 bichir and a jardini arowana. I got a great deal on an unused used acrylic tank. Only catch was the craftsmanship was a little sloppy. Seams are perfect, but whoever assembled it dropped specs of cement on the inside causing unsightly blotchs.
I personally dislike the look of bare bottom as well, hence wanting to cover it. The other downside to the tank is a blue background. Not my preferred choice. I intend to put a 3d low profile background in as well. The slate and or tiles is an attempt to provide a more natural look. The reason for the pots is to assist with cleaning, but as an aquascaping junkie...a bare tank with just fish looks boring. With that said, going for a natural look while keeping the tank clean with these fish isn't easy. Most pots I have found are round shaped or the sides bow out. This isn't optimal as I want to use the smallest footprint for the pots possible while still providing a significantly large enough substrate for monster plants.
In my mind, the benefit to DIYing the pots out of the same material as the floor is that it should, once again in my mind, look more seamless and less forces. I also have some lava rock with plants grown attached that I intend to use to soften the transition from floor to pots.
Video of tiled aquarium. I am thinking something like this but a bit darker.
One other note to the setup, I will have a 75 gallon sump running filtration. First chamber will be a diy trickle tower and tons of media. Than there will be a large foam divider. Next I will have a refugium followed by another foam block to the return pump.
3d background Think something like this
Huge fish, massive waste production, still want it to look nice.
The backgrounds I am considering are.
