I have raised fresh water fish in the past and did a little research then on fish in general. Correct me if I am wrong but from what I understand in order to start a saltwater aquarium the aquarium itself needs to be 30 gallons+ with a heater of course...the regular nitrate, nitrite, ammonia and ph lvls have to be monitored along with the salinity which is a biggy. Id like to raise live coral too in the aquarium... Big questions for me however are...If I wanted to buy a smaller say 5-10 gallon tank or two to seerate fish eggs into would this be of adequate size or is bare minimum 30 gallon even for young off-spring?.....Also since I am planning on breeding ,a fliter which sucks water out of the tank will bring the eggs with it so what are some alternatives to filtering the water?...Oxygenation stones and Tubes seem to work really well from past experiences...Any good hints or tips that I might need to know to get it up and running efficiently?..Easiest salt water fish to care for right off the bat?....I hate to spend a lot of money on fish my wife thinks are pretty and have them die because I didn't do my homework...Thanks for the answers ahead of time
