Thank you for replying John, desperate for advice, i've also heard the Cherry Shrimp is difficult to breed, i've seen a river shrimp on e-bay what looks good will have to look into them as well. At the moment i'm looking at Daphnia, Ramshorn Snails,Louse, Shrimp( suggestions needed for a suitable easy to breed one),Scuds (if they wont take over) hopefully to harvest all these for my wildlife pond (goldfish in there what have bred as well) and to feed my Koi.
If there's anything there what sets alarm bells or any other suggestions please let me know
Thank you
Tony
