I have a bath/pond at my allotment which has frogs in it, it is a new pond and i was given some fairy weed and some oxygenating weed. I now have fish in the pond which i presume were eggs on the weed. What kind of fish are they likely to be ? There seem to be two different types one similar to a stickleback and one which is transparent with an orange stomach. None at the moment bigger than an inch.
