Froggirl Posted July 16, 2022 Share Posted July 16, 2022 (edited) Hello, I have a stable shrimp tank which houses 10 pygmy cory, 10 kubotai rasbora, 1 small super red pleco, 1 adult clown pleco and about 20-30 shrimp. It's been running for 3-4 months. There's also live plants, moss, catappa bark and leaves, etc etc etc Today, I've had two of my newest added shrimp die on me. I don't know why. They were added at the start of July and have been fine until now. I've had one or two shrimp die before but those were due to failed molts. I would also like to add that even though there should be about 20-30 shrimp in there I usually only see 20 max. I'm aware they're good at hiding and I haven't found any dead ones other than the ones mentioned earlier. My parameters: pH: 7,5-7,8 kH: 8 gH: 10 NO2: <0,01 ppm NO3: 1 ppm NH4: 0,1 ppm Thank you in advance! Edited July 16, 2022 by Froggirl Link to comment Share on other sites More sharing options...
Barbvday Posted July 16, 2022 Share Posted July 16, 2022 Out of curiously… how big is your tank? The tank is still fairly new as well but seems like the other shrimp are doing good so far so that’s good news. Ideally there should be 0 ammonia and nitrite but the levels are very low so it should be fine. Did you get the shrimp from the same source? I find that local breeders are best unless you’re sure the pet store acclimated their shrimp properly. Link to comment Share on other sites More sharing options...

The tank is 18g, the 2 shrimp that passed are from the same breeder as some other shrimp which are completely fine, the corys are also from the same breeder. Unfortunately our local pet stores are very bad, I get my shrimp (and cory) online. Link to comment Share on other sites More sharing options...

Neos can be sensitive when getting settled but once established the colonies breed like crazy. Link to comment Share on other sites More sharing options...

I think I added them with the corys on the 6th of July, I thought they would be settled by now but I guess I thought wrong. Link to comment Share on other sites More sharing options...

Add an airstone if need be for added aeration, consider salt as well. 1. Clean the filter and pump itself very well, including the impellers. 2. Add some 100% silicone grease (available at scuba shops or online) or some other food grade lubricant to the impeller shaft as you normally would. 3. Gravel vac the substrate to make sure there isn't a ton of mulm sitting out causing something like anaerobic issues. 4. Test daily and keep an eye on Ammonia, Nitrite. I had a few shrimp turn red, which I was informed is a sign of stress, I never saw anything in the testing results to indicate an issue. I also noticed them flashing/rushing around the tank like the flow was turned off and it wasn't. This was after the equipment issue was fixed. After about 4-5 days my tank showed nitrite, not any ammonia at any point in time. I would suggest keeping a very clean tank in terms of the water quality until you have ammonia and nitrites at 0 and then report back with how the shrimp are doing and their behaviors.

Also, welcome to the forum! Thanks! We have 2 sponge filters which provide plenty of aeration, no issues there or with the filters themselves. Mulm and such is at an okay level, nothing special. A while ago some people on this forum told me I had to change the water once nitrite or ammonia reached 0,2 ppm or nitrate 40 ppm. Shrimp are also behaving normally, some huddle together in a corner and others are out foraging. No issues with the rasboras or corys either.

I apologize about the delayed reply. I am trying to think of how to help. If you can, I would suggest adding some lava rock to the tank if you can. It would act as your ceramic or media for the tank itself alongside your other filtration and really help to try to keep 0 ammonia / nitrites.

I'll try my best to keep nitrites and ammonia at 0, I measured again today after another shrimp death from the same batch and nitrite is at 0 now. Also got some lava rock as well!

nabokovfan87 Posted July 17, 2022 Share Posted July 17, 2022 Are you feeding something specifically made for shrimp? Even algae wafers or frozen worms or some other frozen food might be a good way to "add new shrimp" to your colony and make sure they enter in thriving.

Oh yeah, they get bacter AE, zucchini, shrimp king complete and snowpops and they also eat from the pleco and cory wafers. Frozen blood worms as well. Honestly I'm thinking it's just this specific group, the ones we added before these ones are doing fine.. I'm not sure what went wrong with them though.. Measured nitrites and ammonia and both was at 0 ppm today, nitrate was 2 ppm. All of our shrimp don't really come when we put food in though, but I'm assuming that's because they have plenty all around already? Anyways, I'm completely lost on what's going on.

Yes, that means they are grazing a lot or could point to a parasite or some other issue. Try fasting for 1 day, then feeding, see what happens. I was just saying, whenever you add new shrimp to the colony, dump in some food so they can eat right away. Link to comment Share on other sites More sharing options...
Dkshadowwolf Posted July 18, 2022 Share Posted July 18, 2022 I suggest added a calcium block of some sort. I suggest this, because you mentioned you had 2 deaths in the past do to molting issues. I could be do to a lack of calcium. Even if calcium is not the problem adding a wonder shell or 2 won’t hurt. Link to comment Share on other sites More sharing options...

Hi, thanks for your response! I recently started adding ground up eggshells to the tank. Is that ok?

Might be hard to fast since there's a lot or natural food for them in there but I'll give it a go! 1 Link to comment Share on other sites More sharing options...
Melkor Posted July 18, 2022 Share Posted July 18, 2022 You could occasionally add a bit of blanched organic kale or spinach. Both are pretty high in calcium. Mineral junkie bites or pearls are a good supplementary food as well. 1 Link to comment Share on other sites More sharing options...

I'll look into the junkie bites, thank you. 1 Link to comment Share on other sites More sharing options...

We hard boiled some eggs, took the shells, cleaned them completely, let them dry and then ground them up I think. 1 Link to comment Share on other sites More sharing options...
JettsPapa Posted July 19, 2022 Share Posted July 19, 2022 I just now saw this thread, but you may be overthinking things. If you only found two dead shrimp it's possible their time was just up. If the rest seem okay I wouldn't make any big changes. Link to comment Share on other sites More sharing options...

Well we had one or two more die on us today / yesterday.. but all from the same "batch" which we added on the 6th.. others are completely fine.

That sounds like it might be a problem with acclimating. If that's the case I don't know that there's anything you can do at this point. Link to comment Share on other sites More sharing options...
