Hmm, I think my girls might like that in their tank :p I have some craft mesh and java moss already... I've actually been trying to decide what to do with the java moss, lol.
IMO, you can't be too careful. I have separate clean/dirty water buckets and a different siphon for each of my tanks. When my new girls came in, I created my own siphoning system for their QT tanks by getting a turkey bastor to clean up poo and getting some standard airline to siphon out the water. It was, uh, cheaper than the siphons were, lol, but it takes a lot longer.
Well, 'specially with my girls, I don't want to introduce ANYTHING into that tank, because one sick girl can = 6 sick girls. My boys are in their own tanks, so I don't have to worry about that as much. But if I used one bucket for clean/dirty everything, I'm pretty sure that one sick girl would = 8 sick bettas. (Soon to be 9, I hope :D)
