Cucumber And Bugs?

[The Lady Raven]

I'm not sure if I'm posting this in the right place but...

I just put a slice of cucumber in my tank for my bristlenose plec to nibble on (his first piece!) and, while he was ignoring it, something else wasn't. I came back a few minutes later to find around 20 little green specs on the cucumber - I thought they couldn't possibly be alive and it was the current in the water making them look like they were moving. So I took the cucumber out and they were still 'crawling' around. It's impossible to see what they look like or take a photograph because they are so so tiny. But they are dark green round things that were heavily attracted to my cucumber. Is this a problem? Are they living in my tank and can anyone tell me what they are? Thank you!

Yeah the cucumber was fine, I noticed the little green things in the rocks as well but I hadn't seen them before the cucumber was put in - they were more visible against the light colour.

They do actually. Someone suggested that they might be water fleas. I imagine they've been there for quite a while and I've never noticed them. The fish don't seem bothered by them though.
