We are getting a group of 12 blue mobas and have a couple of options on what tank to use . Would it be better to put them in our 6 foot 230 or in our 160 6 foot bow front or our 160 42 inch deep tank and what would be the best lighting. THESE FISH ARE ABOUT 6 INCHES NOW COULD WE ADD OUR 6 INCH TO THE GROUP IN A NEW TANK WITHOUT ANY PROBLEMS.
