Hinge Beak Shrimps (Rhynchocinetes durbanensis)

Postby Clownfish75 » Thu Oct 09, 2008 7:40 am

Hi all

Well the other day i bought 3 of these little critters, and now i have about 1500 larvae. plus i bought 6 more adults for my breeding gang.

So far i have determined a way to sex the adults. ill try to sort out pics, PaulG will keep me honest on this one!!!

I was wondering if anyone has any experience with this genus. I have them in a round black tank green water each morning. The newly hatched larvae are similar in size to a coral banded larvae ie small. i began feeding with rotifers and given how little the green reduces in the day they must be eating them, I have also added artemia.

The larvae are growing as i have another batch 3 days younger and the older are at least 2X the size.

Any advice please let me know, days to artemia feeding, settlement time.

Thanks

Christian

Thanks Fuel

I have them to about 2 weeks now, had some higher mortality a few days ago but doing ok again now, jus thad reduced water flow through those nights, seemed to cause issues.

Still have heaps, but the low hatch tank has the highest levels of live larvae now.

huge antennae out the front of them too.

just getting a mix of artemia, enriched and new hatch and some cyclopeeze soaked in water.

so i have two camel shrimp in a 20 gal bare tank with a drip system . i added iodine and 30 hours later i noticed larva in the water column not many just a few that i could see . the next day i noticed thousands of crawlers on the glass that were about the same size as what was in the water . what i want to know is do they settle that quickly or is it a bloom of copepods. the strange thing is its a bare tank with nothing but a really thin handful of sand and a slow sponge filter . i dont see how copepods or what ever they may be could populate that quickly.
please help

Hi Amy,

I raised these guys when I was in Australia. I'm sure Christian remembered the hundreds of them. I reared the larvae in a 10 gallon glass tank with daily water exchanges, greenwater and prey replenishment. Aeration is fine for them. The larvae look just like little elongated bugs with long antennas. Settlement was fast, around 3 weeks plus if I remembered correctly.

I never really look at shrimp much but as it turns out these guys are at my LFS all the time. I guess I need to pay more attention.

Luis,

I gave up giving my larval shrimp cyclopeeze as majority of it would just float at eh surface & end up at teh edge of the tanks, even after soaking it overnight.
