Thanks Jenaero...I saw it at the pet store, I'll go get some this week. How do I give it to them, you said crack it into pieces..my babies ar like 2 inches now...how much shoudl I give them?
ALSO, I buy two guppies to put in the tank with the kids about once every 4 weeks...is that a source of calcium as well? I think that only Kaylee get's the fish because I haven't seen Kobe get excited over anything other than his pellets.
