Ok I'm going to set up a small shrimp tank. The fish shops I've found so far don't have any species I'm interested in, and I haven't had time to try to contact the local associations properly yet (sent one email...in English lol). I need a tank somewhere though as 2 months without is more than enough. I can get crystal red shrimp easily so I'm going to try those I think. I've kept cherry shrimp before so know how to keep them alive but they were in with some fish and I think I had all males as I just picked the most colourful ones out at the shop so I never saw any eggs/babies. /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" />

Therefore shrimp-lovers, I need answers! /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" />

- what's the minimum-sized tank I'll need to sustain a productive breeding colony of these?
- what kind of filtration is best to use? Air-powered with a sponge so the young don't get sucked in?
- I was thinking of a combo of leaf litter plus java moss would be ok for decor. Opinions/recommendations?
- is the choice of lighting important?
- How long do the young take to reach sexual maturity?
- do Neocaridina species hybridise if kept together?

Thanks a lot. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

way to go m8.
you should have no problems.
with the cherry shrimp, the colorful ones are the females, the males tend to be either vry pale cherry or some are indeed almost colourless.
i would go for a 24 x 15 x 15 if you can. using either fine gravel, or better still sand. mine seem to prefer the sand as they like picking trough it.
i use oak leaves and they seem to love it along with some java moss. i also have a small piece of bogwood in for them to scavenge off.
lighting is only important if you want to grow plants, otherwise hose a light that bet shows of their colour.
i use air driven sponge filters, the shrimp seem to love picking off them.
as for reaching maturity, to be honest i've no idea of the time scale. i have some black crystals i got in march that have yet to reproduce, they were small when i got them so perhaps they should be at breeding age now.
i keep all my shrimp tanks at ph 7, and medium hardness. temps around 74F.
some cardinia and neocardinia will hybridize, so i keep all mine apart. however, there i a chart here that may help. it's by noway 100% but gives a good indication.
hope this helps.

That's really helpful mate, thanks. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> I'll just get the one species if hybridisation is a possibility. Any type of light you can recommend? I usually use white Sunglo tubes...

One more question...maintenance. With no fish in the tank will I still need to do weekly water changes?

nice one matt, good luck /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
I'll go with what Keith said, sponge filter, sand, wood and plants.
Lighting, shouldn't matter what you use aslong as it's suitable for the plants you put in but for photography purposes i'd go for something with a kelvin rating of about 10-14k. Too much lower than 10k will give off too much yellow.
Yes I'd still do a weekly waterchange /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Cool, cool will see what lights are available over here then. /cool.gif" style="vertical-align:middle" emoid="B)" border="0" alt="cool.gif" /> Is the filter really necessary if I keep up a good maintenance regime do you guys think?

Logically you'd need a filter for the bacteria colonies that will break down the waste produced, so the sponge filter sounds good to me.

Mature, sensible signature required for responsible position. Good prospects for the right candidate. Apply within.

Mark, logically yes, but I've kept many fish without filter over the years and was wondering if the relative bioload of the shrimp will be small enough to consider doing the same...

Purely being nosey, but is there a reason why you don't want a filter in the tank?

Not at all mate, was just interested really. I'll get a small airpump and sponge filter if they have them. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Hi Matt,
I've got 5 shrimp tanks without filters ,just a good supply of air ,the bacteria in the gravel,on the wood and my java fern seem do the trick (loads of fern LoL muffles the water flow also ) I've also had crays (Cherax q. ) living and breeding in tanks without filters. Heaters also dont look nice when the lecy bill comes in so I do without them . You might need a fan to keep the temp down in your new town though !
All the best bud,
G. John

cherry's and the orange/yellow dwarf have been fine without a heater with temp ranging between 21.6-24.5C that i've noticed. I've moved the red's out incase they interbreed with the others.
Red Crystals apparently prefer cooler than many shrimps, 65f-72f but they still bred in my lfs at temp of about 26-28C, undergravel filter and no heater. The PH is higher than reccomended, 7.2 as opposed to the 5.8-6.8 but they're fine. Keith has seen the babies /wink.gif" style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" />

EDIT* I'd say stability is the key

Brilliant thanks all! Will omit the heater then. I think I might have to use bottled water as the tap water in Barcelona is bloody awful and rock hard. /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" />

if your water is going to be too hard and have to use bottled then get the filter as you won't need as many water changes, in theory.

personally i would go for a filter if you have poor water.
i've seen john's tanks and they are buzzing with shrimps, so no filter works.
as for temp, well my fish house has been up to 31C the last week or so and all the shrimps look fine, so temp might not be a huge problem at the mo, but may be if it gets to hot.

Good boy, glad you're getting a peniculus spurcamen (sponge filter) /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" /> /wink.gif" style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" />

Peniculina (class Ciliatea, order Hymenostomatida). A suborder of ciliate protozoa in which characteristic bands of cilia (comprising the peniculus) occur in the cytopharyngeal region. Body cilia are arranged uniformly. There are several families, including the well-known genus Paramecium, found in aquatic environments.

OR:

Peniculus
1 - From the prodelision used by Plautus in his work, "Menaechmi". Formed from the words "Penis" and "culus", it means "Precious penis".
2 - conventionally, a sponge.

Spurcamen = "filth" in Latin....

So you're close mate...

Ps - scientific names aren't necessarily in Latin they're just specific to a given species, but now I'm just being a geek... /blush.gif" style="vertical-align:middle" emoid=":blush:" border="0" alt="blush.gif" />
