      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.

      Here are a coupe of pictures so you can see what I mean, it just isn't going as nicely as before? I can only assume it is the different substrate, still it will get there I am sure and the shrimps seem happy enough and the plants are very slowly growing and going a bit greener than they were. As can be seen in the pictures the shrimp are totally uninterested in the shrimp lolly (or spinach) at this point so I guess there is enough biofilm? It all looks a bit drab, uninspiring and unhealthy? I may remove the Java fern in the middle at some point as I do have another greener (quite small though) bit floating around in an old tank? Simon

      Those parameters are perfect! I think I experienced the same with the algae on plants when I restarted the caridina shrimp tank, but mine seems to have almost cleared up as well - taken months though. One of my failed attempts with tap water many years ago I had PRL and PBL and it did look much more interesting than just the one colour. They didn't live long enough (maybe 6 months) to really know what the offspring would look like though they will still be red crystal or black crystal  so they should be fine together. If one colour does become more dominant then you can always get some more of the lesser coloured ones anyway in the future.. I did get red babies but no babies lived very long as it was tap water! I would try transferring just some shrimps (may be a third) over to the new tank if you are sure it is cycled and see how they go in a week before transferring the rest over? You won't want too many in the tank anyway if you will be messing about with plants/layout still and you won't loose the whole lot if something does go wrong? Maybe also put the Amanos in the new tank for now so the ones in the old tank won't be fitting with them any more for food? Simon

      Update. I filled the tank, unfortunately, there was some melting of plants and some light hair algae( algae is only on the leaves of some plants, nowhere else?). Adjusted my light schedule and intensity. Things are looking better. Did a 70% water change, remineralized with GH+ powder, and clean tonight. Levels are as follows:   PH: 6.4 Temp: 75 GH: 6-7 KH: 0-1 TDS: 140   Wondering  when I should transfer the shrimps... I want to order 10-20 more CRS, and I’m considering mixing in some CBS. I’m not concerned with selling these, so it would be neat to have two different colors. I know the Black coloration is dominant, but, from what I’ve read, I’ll still get reds from offspring in two-ish generations. Someone said expect 25-30% reds. What do you guys think? My  additional plants haven’t been delivered today, so thats a bummer.

      Thanks, the ol' iPhone 6 rarely makes me happy, but if you take enough sometimes you'll get one good one!

      Nice shrimps, I like that blue bolt in the 7th photo, I want one, I also just purchased today another 8 Red Wine to join my other 3 in the tank, along with one amano shrimps and 23 thai micro crabs.
