The opae’ula in the 2.5 gallon tank are bright red, unlike the shrimp in the other tanks. This is the only natural sea water + bottled water tank (1:1 ratio) in my collection. This is also the only tank that is close to the west window and receives a lot of direct sunlight in the late afternoon. Update 11/26/15: I noticed a slow leak in this tank about a month ago and moved the colony into another tank. I won’t be using this tank again.
