Yeah, will be ok. If you've no tropical flakes (which i'm presuming you haven't!) how about giving your fish a treat of a slice of cucumber weighted down? Mine go crazy for it. They also like a couple of peas that have been cooked and squeezed out of their skins.
Excellent. Many thanks for your replies, i will try the peas and cucumber now!
I ran out of fish food and only have goldfish food till saturday:-/
Thanks again, Steve :-)
