My water has finally gotten to perfect conditions! It's been a Long Cycle... pH 8.2 - SG 1.0235 - Nitrates 0ppm - Nitrites 0ppm - Ammonia 0ppm I went to my LFS to get the pair of black clowns I had been wanting since I started my tank and have them test my water as well. The kid working there told me if I eventually wanted more than two clowns that I should purchase all of my clowns at the same time as adding more later would cause territorial problems. Right now I have a 125 gallon tank with a 35ish gallon sump and No Fish or CUC. I was planning on starting with a pair of clowns and some snails/crabs as a CUC. Is this kid trying to sell me fish to make a quick buck or is he correct? I would like 4 of the orange clowns and a pair of 2 black clowns. Would it be ok to buy the 6 clowns together, each are about 1" or less in length. If I buy that many at once, should I buy some Live Rock to help seed my Dry Rock (125 pounds of Dry Rock already in tank) or buy my pairs of clowns at different times? I don't want to overload my tank with a big bio-load but I don't think 6 tiny fish would really overload the tank. I am planning on putting some Dry & Live Rock (or Sand, Recommendations on this are welcomed) in the center chamber of my sump with some Chaeto & Copepods. Please help! I don't want to kill my critters or make them suffer/struggle to survive. Would it be okay to put two pair of orange clowns in with a pair of black clowns? As I said, these will be the only fish in the tank and it seems like 6" worth of fish would be okay in a 125g tank. I would like to have my tank stocked with 4-6 Clowns, a Yellow Tang, Blue Tang, a Goby or two and maybe two different types of wrasse. That's my "Wish List" for now. I may want to add some different species later but this is my list of what I want so far... I really am more interested in a Coral Reef Tank than a "Fish Tank" I want to introduce as many types of Coral as I can over time. I love the soft corals and some of the branching corals. Basically, I need to know if the orange & black clowns are compatible tank mates and if adding 6 that are less than 1" each at once with a CUC is too much at once. I don't know if this kid is BSing me about adding them all at once to get a bigger sale. I do know that clowns can be territorial but is he correct about adding them all at once? He told me adding more later could cause issues between them over territory in the tank? These will be the only fish I add for at least a month. Also, what is the temp range (in Fahrenheit) of water that Clowns like best? I will add coral frags as I can afford them but will probably wait at least 2 weeks before adding the first frags to make sure the fish are staying healthy.
