Hello folks! I'm new to here, and just want to ask a question. This visitor to my pond is the third this summer and I'm wondering if he's friend or foe?! I suspect the latter and have escorted him from the premises! The last one I saw had a baby (I think!) and left it clinging to my oldest goldfish but luckily I spotted it straight away and removed it from his skin gently. Any advice gratefully received. Thank you!
