Hi, I have a 4' tank that is 90 gallons. I have a pair juvenile tank-bred nemo fish that stay near the powerhead on the top corner. I really like these fish. They are cute and very easy to feed. I dont have an anemone. I have had them about 6 weeks. Can I add another pair of clownfish? I do have a 30 gallon tank that doesn't have any fish that I could move them to if it doesn't work out. What other type of clownfish would give me the best chance of success? Does anyone have two pairs of clownfish in a 4 foot reef tank? My other fish are two anthias, that I recently purchased and find very hard to feed. I would not add the clownfish for a while. I am just thinking about my options.
