CRS Breeding

Hi All,

I've had my CRS tank up and running for almost a year now and i've had a few berried shrimp over that time.

I never done any water changes but only top ups. The TDS stayed under control but feel like i need to start doing some water changes. I am looking to do a water change of 10l every 2 weeks with a top up of RO water in the middle . would this be enough ? It's a 60l tank. The water is dripped in through a 6mm hose. 

Will this help with breeding? I'm from Scotland so we are currently in winter and have heard that breeding declines in the winter,

It may help with breeding as it does tend to encourage moulting etc. It would be advisable to change the water as planned anyway for the general health of the whole tank so I would encourage that! As you say though, it may take a while as we are mid winter and many people experience slower/no breeding in that time, not everyone though.

An initial large water change of 50% is probably required to get rid of as much built up waste as possible.

Then drip back in the water matched to ideal parameters for your shrimp.

You can maintain it thereafter with a 3L (5%) to 6L (10%) fortnightly water change - depending on TDS readings. Even if they don't breed over winter, the regular water changes can't do any harm.

      Great idea! Please document your journey here. I have no experience with marine shrimps, so cannot help you. But what you have listed above seems like a sound plan to get started.

      That sounds like a fun project and look forward to hearing how it goes!  Hopefully someone will have some useful advice/tips etc?

      I have an idea. And considering I’m terrible at being concise, I’m sure it’s gonna take me a while to explain it.   Essentially, I want to do a nano marine rockpool tank, with just crustaceans and molluscs (and perhaps a seastar or two). And I really don’t know how plausible it is, but I’m pretty intent on finding out. I don’t know if anyone here has any experience with marine shrimp, but I figured I may as well see if any of the Aussies here are familiar with the shrimp I want to keep. So this species of shrimp is actually the species that got me into the hobby! I found them on a camping trip, and they were just so active and engaging, and I just fell in love. Then I went home, did a bunch of research, and got an aquarium. They’re part of the reason why I’m so interested in shrimp. Now I’m on holidays again (in a different place in Vic) and they’re everywhere in the tide pools. Millions. The species is ‘palaemon serenus’, the red-handed shrimp, and they grow to about 6cm for big females (which I discovered last night) and I think 3-4 for males. Just from observation. They live primarily in colonies of 10-30 under rocks during the day, venturing out when they feel safe, and going everywhere once it gets dark. They’re omnivorous, eating pretty much everything they can get their little claws on (including my fingers and toes). They look rather like freshwater macrobrachium, to be honest. I’ve had a look and it’s legal to collect from this location. There aren’t limits on anything I want to collect. So, I’m thinking I’d do a 20 litre tank for the meantime (until I can get some awesome 30ish litre low-boy tank). I’ve got one at home that could be set up as soon as I’m back. If I take home a big rock and sand, then I should have beneficial bacteria sorted, as well as a food source. The rock would have plants and a bit of algae and all the other good stuff you find on the rocks they like. Other than using salt for water changes, I’d run the tank like a freshwater tank - sponge filter for filtration, freshwater light, no heater, fortnightly or monthly water changes. I’d love to add a couple little fish if I can catch them, but I have no idea how to identify whether they’ll grow or not. Same deal with the majority of crabs (although I have ID’d a few species that would work). And unfortunately no nudibranch either… although I found the CUTEST little one last night. They’re apparently super specialist in terms of diet, and I don’t have the time to observe one for hours to see what it eats, ID it, work out how to cultivate it, and all that. So, that’s the plan. I would love any advice, recommendations, or criticisms you have. I understand there’s a good chance this could be too ambitious, and the well-being of the animals is number 1 priority, so if it sounds like it’s a bad idea then I’ll just scrap it. But I’m pretty keen on finding out a way to make this work.

      I have had fungus each time I set up a new tank, but it has always just disappered on its own after a month or two, and has been varied in appearance each time!

      Had a go searching / feeling throught the substrate for the tabs but no luck.  They might have dissolved or become soggy so I can't  feel them.  I have a bucket sample of substrate brewing at the moment for a 24 hour test and its already steadily rising the TDS.   Looks like a just wait and see...... Thanks for all the help as ususal it is appreciated.  Dirk
