I am still in the planning stages on my 210 gallon 60x30x27
the tank will be all marine planted. little to no coral.
How many Gobies could i keep in that size tank and what kinds cannot share a tank that size.
the must have gobies are tiger watchman, two spot.
the only other fish that i have is a pair of tomato clowns.
Two spot gobies need a large sand bed with rock structures which create overhangs. They are copepod eaters so the tank must be very mature and/or have a producing refugium. I can not begin to answer "how many" type questions.
