Can you tell us what all your anemones are. Kinda hard to tell. The BTA's are very unusally colored.. Nice looking group though..
Purple are sweet!!! Are they kinda like condy's? Is the water cold most of the time in UK? I know nothing about that ocean area. Did you find them in tide pools?
Wow you have some awesome anemones growing in your waters. In NC we don't really have anything,pest nems,warty different colors,tubes. I have some local warty nems they are cool and stay exposed to the water at low tide.
welp I know for sure about the nems! But spiny box puffers,pepperment shrimp are very common. But I only have one tank now with a GBTA so no puffer.. They are tiny when people see them as they are only near the shore when young,like a small gumdrop. Its funny cold water nems have such nice colors. I think the coldest the water ever gets here is in the upper 40*'s if that low.
