I thought this tip might be useful to those with small goldies.
I like to feed my goldies fresh foods like peas, melon, lettuce, etc. Well, my fish are still quite small. The lettuce is easy because I can just clip it to the side of the tank. But with foods like peas, grapes, melon, cucumber and so on I found that it was time consuming and messy trying to mince them into small enough pieces.
Here's my little trick. I use a garlic press just like <a href='http://www.surlatable.com/common/products/product_details.cfm?PRRFNBR=5692' target='_blank'>this one.</a> I just pop the amount I want into the little reservoir and, presto, instant perfectly sized peas or what have you. Simple as that!
Hope that it's a help to some of you!
