A VERY soft siphon is reccomended to ensure that no fry get accidently sucked up. I reccomend a filter and heater that you can adjust for the spawning cycle. (Sponge filters work fine). As for spawning tank sizes, you can start out with a 10 gallon. For a grow-out tank, find something no smaller than 20 gallons. (I like to use a 30 gallon to ensure room). However, it is possible to do the entire spawning in the grow-out tank.
