      Hey guys, I’m really wanting to get freshwater crabs, and the only ones I’ve found are A. Lacustris and A. Laevis. I can only put them in a 110 L community tank for now, but may have another option in the future. The tank is stocked with a large school of ember tetras, some rocket killies, some endlers, some tangerine tiger shrimp, and a pair of apistogrammas. Rare aqua advised that A. Lacustris would likely be eaten by the apistos, so the obvious choice would be A. Laevis, because they’re larger... right? But I’m worried that they might predate upon my shrimp, so wanted to hear some advice and opinions from more people with experience keeping these crabs.
      Cheers!

      I've been avidly watching these little guys since receiving them yesterday, and I thought I'd make a new thread for the observations! Fist up some pics!
      Next, some interactions with shrimp. First up, a pair getting intimate (or failing to - looks like the male was just seeing if she was in the mood) while ignoring some nearby shrimp.
       
      Next, a male getting territorial and chasing off a sunkist neo. Sorry about the lower quality - camera was set to low res accidentally. This movement is different from how they attack snails, so I think it's a territory issue rather than a hunting attempt. If you slow down the film you can see he raises his body and claws really high as though to look intimidating. But I'm not a crab expert so I dunno.
       
      Next a shaky-cam quick-and-dirty video evidencing snail-eating prowess. Don't watch if you get motion sick!!
       
      Next up, a rookie attempt at a close-up film. A bit shaky and focus is off, but you can see the female's cute face.

      G'day jayc, Many thank for your informative reply. I have looked on eBay and found this Macro Plant Fertilizer.  Would you recommend this if not could you tell me another you would suggest I purchase. Cheers Perry

      Hey Sonny, please don't take my post the wrong way. There was no need to apologise. We all start somewhere and we learn along the way. Sometimes it's a trial and error. I was just trying to share some knowledge with tank cycling so that you didn't need to go through trial and error learning.  Rather than following youtube blindly with 2 water changes a week, you now know exactly when you need to do water changes. Your specific tank might only need one water change a week while cycling. Or if pH drops too low, it might need more than that. But you are now armed with that info.

      It's a moss of some variety, but it's not easy identifying what type of moss when it's all bunched up like that. Java Moss is the most common, so if I was to guess, that's what it is. Moss will grow any where. You can just drop it onto the bottom of the tank, anchor it to a drift wood or rock, or wedge it between ornaments so it doesn't float around.   Not quite sure what the other plant is. It could be an Amazon Echinodorus Bleheri sword or a Cryptocoryne Wendtii. The one with brown/yellow spots is a very unhealthy specimen due to nutrient deficiency. If you set up the new tank and let it run with no livestock in it, you can treat the plants with lots of light and Macro fertilisers.  The old leaves cannot be saved, but new leaves should be green again. Look for aquarium fertilisers that are labelled Macro or contain Potassium and Phosphate. A fert with Iron and trace elements won't hurt either. An All-In-One fertiliser should have Potassium, Phosphate, Iron and trace elements, so look out for that. Just make sure you change out the water before adding any shrimps in. We don't want to add shrimps into a tank that has too much ferts, as that will have a wildly different water parameter that the shrimps prefer.

      That will be fine, as long as the hose they provide is long enough.

      Yes. The bacteria will be reduced to suit the load of the tank. Likewise it will increase if there is more inhabitants. But this process is not instantaneous of course. That's why you don't add a huge amount of new tank inhabitants in one go.
