I suppose this question might go to UK residents or anyone with this frog which isn't native to where you live. The other day I went into the back garden to continue digging a wild-life pond but as I walked past the pond with fish in it I noticed something a the bottom of the pond. As I had a closer look I noticed a common frog latched its arms around one of the fish, at first I thought frog-on-frog as how the one on top looks but realised they don't normally start mating yet. I grabbed a net and it took me a while to catch them, finally did and took me a while to detach them while being gentle. I seriously don't think the frog was trying to eat it as the fish is proberly a little bigger. Any help would be really usefull. Thanks.
