Soccer And Fish

[Meds081603]

I am a soccer coach for my son's team. We just had our end of the year party and as part of my gift from the parents I got a $70 visa card. I am getting some dog bones at drsfostersmith but will still have around $50 to buy some fish stuff. The only thing I need right now is some food and a couple sponges. My question is this, if you had $40-50 to spend on fish stuff but didnt really need anything and don't need/want new fish, what would you buy?
