Question Why are my shrimp dying?

Hello,

I was wondering if anyone can help me determine exactly what is killing my shrimp?

I have a 10g partially planted tank with a mixture of now 13 shrimp (3 orange Sunkist, 4 red rilli, 6 RCS), 1 rabbit snail (+2 babies!), 6 MTS (+2 babies!), some tag along ramshorn snails and bladder snails, 1 mystery snail, 1 nerite snail, 3 glow light tetras, 1 kuhli loach (very happy fella). There are two java ferns, some frogbit and some java moss along some driftwood. The drift wood is from my tank setup I had setup at college (before corona hit...) so all the tannins were already dissolved out. There is also 1/2 of a sungrow betta leaf (Amazon link below for description), which I boiled most of the tannins out of.

I do 20% WC every 1.5-2 weeks and use seachem prime and stability with the WC. My most recent WC was 3 days ago. I just took the parameters for the tank which are listed: NH3/NH4+ — 0ppm, NO2- — 0ppm, NO3- — 5-10ppm, KH — 53.7ppm, GH — 196.9ppm, Ca2+ — 80-100ppm, pH — 7.2-7.6. All these have remained consistent besides the nitrates which have lowered from 20ppm over 1 week. I only began measuring GH/KH today and Ca2+ two days ago (measured at 60ppm then).

the shrimp have been randomly and slowly dying since I have gotten back from college. I had the tank cycled for 5 days with the snails and plants before I brought them back (originally just the orange Sunkist and the loach+tetras) and the parameters checked out before acclimating the shrimp and fish. Only one Sunkist has died. 3 red rilli and 3 rcs have also died starting after 1 week of being bought/added. I did see a couple molts in the tank in the first couple weeks but haven’t seen any in the past 3 weeks. Some days I’ll have 2 dead shrimp and then a week later another randomly dies. I saw one today that looked dead and when I tried to remove it it moved its swimmers and legs so I let it be. Then later I checked on him and he was dead .


I believe this is a molting problem caused by low GH (specifically Ca2+). I have included the picture of the tank and the food I feed them with below. I feed them every other day with either 1 algae wafer or 2 shrimp pellets and only as of recently I have been adding ground eggshells.

please let me know your thoughts on why my shrimp keep dying and/or how I can prevent more from following the same path as past shrimp have!


thanks! Always open to feedback to learn more!

update: TDS is 368ppm and temp is 72.5 ºF

The GH/calcium should, theoretically, be fine. You should not need to increase it.


If you purchased adult shrimp, especially if imported shrimp, that could be #1 issue. Number 2, they might be getting too much protein in their diet and need more algae/vegetable based foods. (many "algae" pellets are actually algae infused... with algae being the 5th-9th ingredient) Third idea, maybe not enough oxygen?

Could also try dripping the water back into the tank after doing water changes.

I believe O2 is ok being that. There is a powerful bubbler, however the shrimps were on the larger scale when I got them...

I’m going to try feeding bleached veggies for now and no pellets for at least a week.

Zoidberg hit on it but didn’t go far enough on monitoring, gauging KH, GH, PH daily a flatline it as much as possible. If your seeing daily flux in PH, KH or GH fluxuationns you need to to look at source rather than parameters in tank.
