clownfish breeding

hi all im gonna be starting up breeding for clownfish eventually and was wondering do u think a 10 gallon tank a 20 gallon and a 30 gallon would do for this, and also what size heaters should i get for these any help on this subject would be a big help thanks ;D

 

Will they be connected in series or just as separate tanks, will it include a sump for any kind of filter that might add to the water volume?

 

Do a little reading here :

Breeding Clownfish

and

Breeding Clown fish

 

yeah im thinking of having a sump at the bottom you think that would be better

 

read a lot. the only reason I'm even attempting breeding fish is because my dad has been doing it since before i was born. i still remember when i was like 4 yrs old sitting at our bar in the basement watching my dad take baby cichlids out of on of his fish's mouths.
I was the luckiest kid growing up. i had 2 stingrays, 4 (24") red tailed catfish, and at least 35 other tanks filled with fish coming in and out.
