CWC Shrimp

Recommended Posts

I am new to shrimp keeping and saw this shrimp available from a few online retailers for a relatively cheap price, problem is there seems to be no real information out there about these guys.

I bought some but the survival rate hasn't been great, maybe 20%. I know they are not as colourful as other shrimp but I like the idea of keeping a native shrimp that will breed in freshwater.

Can anyone share any info/experience on these shrimp? Or direct me to a source, I'd appreciate it. For example, I have no idea about:

What are ideal water parameters?

Are they easy or difficult to breed compared to say neocaradinas?

What size do they eventually get to?

Thanks ?

I would treat them with the same water parameters as a Longirostis. 

Here is a quote from Nogi in the Article section regarding Longirostis ...

"Hardness ranges from 0 KH and GH to 8 and 10 degrees of dH depending upon season and the creek where they occur. They have been kept at higher KH and GH and prospered under these conditions. pH is the least important parameter as the pH in their habitat changes from wet to dry season; lower in the dry season because of the leaf litter, higher in the wet because of increased water flow. Ranges from pH 6.6 to 7.4 are appropriate in aquariums.

Temperature ranges from 16°C at altitude to 28°C lower down. Temperatures are highly variable year round. In some streams that run from the highest mountains, it is warmer in winter because of lower flow at this time. Similarly, water can be 24°C during winter because of ground water inflow into the creeks. After summer rain, temperatures can be 16-18°C. "

I can't comment on breeding difficulty.

And as for size, the females are bigger, and get to about 3.5cm. The males are smaller and get to about 2.5cm.

Hi jayc, thanks for the information, I noticed you replied on my earlier thread as well and I didn't thank you, so apologies for that. 

Those parameters nearly fit with what I've got at the moment, although I probably need to bring my GH up, I'm using rainwater, but adding LCA shrimp additive.

TBH I suspect my reason that I lost shrimp early on was a few rookie mistakes. I read that they love biofilm and went overboard adding driftwood that had a tonne of biofilm but didn't realise that in excess it could suck all the oxygen out of the water. I'm only keeping one piece in the tank now.

In addition, i thought that because I was dosing seachem stability I could add shrimp earlier than I probably should have.

The ones in the tank remaining seem to be doing OK.

What aeration have you got in the tank? External filter or only and air filter?

Yeah, that is a big mistake many make.

I have an old aquapro 380 with the trickle down filter up the top, but I initially had to put a bit of sponge in the intake to prevent the shrimp getting sucked up. That really restricted the flow. I've now replaced it with a proper stainless steel mesh intake cover, so flow is now good, and today added a sponge filter as well for extra filtration and aeration.

That should be enough for aeration now. Good work.

      Great shot of Big Mama!  I reckon, 1 week tops for hatching.

      Great photo and news. The eggs are fading yellow but there are eyes so all looking good and there are a lot of eggs! Probably about half way ready to hatch.

      Let's hope the big mama can lay safely those eggs

      Sorry, I'm not in that area. 🙃   I prefer Glass tanks. Acrylic scratches way too easily. Often while cleaning algae off the sides. And once it's built up enough scratches, viewing gets obstructed.    Often going with LARGE tanks, you start to fall into custom built stands. So don't be surprised if you cannot find anything suitable.

      The easiest way wouod be to go to an aquarium shop and get a tank with a cabinet made for that tank, as that should be able to support the weight, as water in any large quantity is very heavy. I suspect it would have to be a glass aquarium at that capacity, otherwise the plastic would have to be very thick. It is possible to use a non aquarium specific piece of furniture but as you say it is quite risky, though I did help a friend do that by strengthening a nice decorative piece of furniture they had that they wanted to put a 350L tank on. It has been doing the job for 10 years but also bear in mind water marks, and we had to varnish many coats to make sure water doesn't soak into the wood etc. Its not really worth it in reality, it cost a lot of money to buy all the wood/stuff to strengthen it so was probably no cheaper, and a lot of time doing it. It may be dearer to get a combo tank and stand but much much easier and safer, and only you can know what ones you llike the appearance of? I would start off going to local stores and seeing if they have any you like, and even if not it will give you ideas?
