Retirement and forum shutdown (17 Jan 2022)
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin

I assume they are some form of daphnia, can anyone confirm and also does anyone know if they are harmful to the shrimp or crabs and how to get rid of them...

Unfortunately there are no successful breeding report, though someone had lavae that lasted 9 days.
I have just shot another video and will post when it uploads. In the meantime here is a link to models of crab lavae and they match in all the key points, eyes, long fanned tail bit, spike out of th "shell" etc.

I will be watching these very carefully over the next few days.

The latest batch of crabs are so small it is possibel they are the same species but I have my doubts as their proportion of body to legs and their movements are so different. I don't really mind either way, but if they are the original, I have a bit of growing on to do first!

Also have you kept red claw crabs, would you advise them to be safe for a community tank or not?

I also got some more crabs from a different supplier but they turned out to be about a quarter of the size of the originals and they had larvae after only a few days, microscope video of them here:
Now I just need to figure out what species they are and how to raise the larvae!

Here are a couple of photos:
Real L. nayianetri - female with eggs, these crabs are tiny, carapace about 4mm across.
Real L. nayianetri - front the front.
Mystery crab that was originally bought as L. nayianetri, these are much larger carapace of about 10mm.

Any ideas on how to grow them on successfully Darragh?

The short answer is no

The answer is in some combination of above. If only the wholesalers would be more accurate with catch locations you could learn so much on the conditions of their natural envirnoment, however numberous locations have been given so far.
It seems 6 days is as long as anyone has kept teh larvae alive and there is not much detail on the conditions they did that in.
I managed to extend from 24 to 72 hours the lifes of the second batch using 24hr lighting, green water and spirulina powder. However I strongly suspect that based on the volume and frequency of larvae produced that these are like ammano shrimp and require a marine cycle to go from larvae to crab. I have plans to try a few things, just need the time to play around.
