Whats good for this tank?

[Giga]

I'm looking for a good mantis that would fit my tank that is 25"x21"x9" it has a large footprint and is about 20 gallons so what do you guys think?

it's the tank on the left

Is there a top to it?

 

[Giga]

no rimless

"Even in failure, your only a failure when you quite trying."

Not that it matters, but you spelled "quit" as "quite" which makes your signature not make sense

How far down from the rim of your tank will the water level be? I rarely saw it happen, but my mantis would swim up the side of the glass to the water level from time to time.

is that foam not toxic to the tank? If not it would be kind of cool to create some aquascaping with it.

No the foam is 100% safe for marine use and as you see there is another acrylic one on the right side they are both going to be planters for mangrove and the left one has a pvc tunnel in it for the mantis the foam is also going to be covered in epoxy and sand to make it look like rock/more natural look. The water is about 1.5" down from the top so i'm not really worried. when it's done it will look like a tide pool (of death )
