[roydon]

:dk: Can anyone please comment wether glass shrimp in a fry tank is a bad thing and do they eat the live fry.

tank 30' x 20 x 20 large foam filters x 4, 20% water change daily 500++ fry in tank sizes range from 1cm to 2cm common albino short and long fins.

Also can I feed cucumer to them at this size with seeds removed

At the momment just feeding HBH algae flake ground into powder

Hi all,
I'd be very wary of Glass Shrimp, or any other shrimp with obvious pincers.

I've used both Red Cherry Shrimps and another crustacean Asellus as fry/egg guarders successfully, although I'm pretty sure we had a thread where
RC? shrimps had eaten Angel-fish fry.

Hi Roydon
I have used Cherry shrimp to clean my ram, cacas & angel eggs, they keep fungus at bay to a point. I've only ever seen a Cherry shrimp eat dead fry, never seen one catch a live one and eat it. Not that I'm saying it couldn't happen. But I've not had it happen...
Glass shrimp I can't advise,
But I wish you all the best...
Oh and when feeding cuc you don't need to remove the seeds...just cut and place in tank ..fry will take vegies soon as they are out of the cave and their sacs have been absorbed.

Hi all,

I originally got the idea from here: http://www.aka.org/aka/modules/newbb/viewtopic.php?viewmode=compact&type=&topic_id=783&forum=1 The Apisto, Plec and Cory breeder Larry Waybright "Apistomaster" is one poster on this thread.

I'd used Asellus (Water Louse) before, and this is a very old idea, and has a real scientific reference. [ame="http://en.wikipedia.org/wiki/Asellus_aquaticus"]Asellus aquaticus - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Asellus_aquaticus.jpg" class="image"><img alt="" src="http://upload.wikimedia.org/wikipedia/commons/thumb/b/b0/Asellus_aquaticus.jpg/220px-Asellus_aquaticus.jpg"@@AMEPARAM@@commons/thumb/b/b0/Asellus_aquaticus.jpg/220px-Asellus_aquaticus.jpg[/ame]
Oseid, D. (1977)
"Control of Fungus Growth on Fish Eggs by Asellus militaris and Gammarus pseudolimnaeus". Transactions of the American Fisheries Society" 106 pp. 192-195. The species investigated was the American Walleye, so basically a big perch (or Zander).

"....Egg mortality was 100% where fungus was not controlled. Both Asellus and Gammarus eliminated fungus-related mortality. Gammarus caused about 15% mortality for both eggs and fry. Asellus did not cause mortality for either stage."

The other invertebrate I've used is MTS (Malaysian Trumpet Snail), Ingo Seidel mentions them for egg cleaning in the "Back to Nature guide to L....".

Hi Team,
I use my shrimp to help clean up and left over waste products eg: food and feaces material that im not able to get to with my battery operated vacum, there just really there as a support for a clean tank & a great protein source for my cichlid colonys

With Thanks
