Although 90 gallons would be best, as would a larger tank for any fish, I dont understand why a 50 gallon would not be sufficient. I also dont understand why you would need 40 gallons of water to support these fish, as they live most of their lives on land, using the water for occasional swims, chilling half in and out, and also getting more water to breathe on land. I would think it sufficient to use a fourth of that to support 4 fish, so long as they have muddy land to live on/in.
so, thats where I am confused. why would it be minimal to use a 90 and 40 gallons of water?
