Hundreds of live things appeared in year old tank??

[davi135]

Hi I have a seahorse tank that has been establishedfor well over a year.I have just now seen hundreds of these things in my tank, they are too big to be copeods and don't look like amphipods so don't have a clue what they are. My ea horses re not eating them but maybe they were before i looked and are now full. Any help appreciated.

A picture would help... Are you sure they aren't babies???

You're probably going to have to go through spam filters and your picture won't show right away

Are they crawling around on the rocks/glass or do they appear to be swimming?

Can't tell from your pic.

Oh right, if you zoom in the one on the bottom.left s relatively clear, it appears to have a distinctive head and four 'legs'

Munnid Isopods perhaps? This is just a stab in the dark being that the picture is not showing up for me for some reason.

Do you have any shrimp in your tank? (pair) If not, then what your seeing are probably Mysid shrimp. These will often hitchhike there way into our tanks via live rock, corals etc.

Shrimp larva...that is soooo cool ;)

[nitrodude]

I recently noticed some type of shrimp larvae in my tank.
They stay in a relatively small area a few inches away from where my 2 cleaner shrimp are.
Not sure if they are cleaner shrimp larvae or mysis. They look like tiny bait shrimp.
Noticed em a week or two ago and just checked and they are still there.

Looks just like these - cool
