thanks for all the input. also i have a quick question about my clownfish. I have tried 4 different types of food, frozen brine, frozen mysis, the same pellets they were eating at the store, and a flake food. They get very excited when i put food in the water, they start swimming at it very quickly, then stop and dont eat it. They act like they are and then they dont. Is there something else i could do to entice feeding?
