Alright, the tank dimensions are
29.5 inches wide/across
18" tall from base to top rim of tank
and it has a little bow to the front of the tank.
15" at edges and 17" in the center at the bow
As for the Clam, I would love to have Discus too but I don't.
Kinda thinking of a bigger tank anyway, but heck I don't even know if I can handle it
Also the costs and time of taking care of so many little creatures.
There will need to be a bunch of time spent to make sure that everything will work in harmony, lol!
