Mysterious Death of Shrimps?
Hi, I have been keeping shrimps for around 8 months nows. With cherry shrimps initially in a small tank and moved on to a 2 ft tank. The reason to move was because my small tank bedding was contaminated with nitrate and alot of shrimps died. and mainly, i wanted a bigger tank to enjoy the shrimps.
after changing, i kept cherry shrimps, sakura shrimps and tiger shrimps. bought them all at crs haven at tampines. however, for the past 5 months, since i changed to my 2 ft tank, shrimps start to die every week. at least 1 shrimp will die every week, sometimes 1 each day. for the past 4 days, 1 died each day. was wondering if anyone knew this is normal or if there is some problem with the tank? i asked crs, they say it's normal for shrimps to die now and then... ?? here's my tanks env. 2 ft tank, normal filter, 1 fan. temp - 28 degree nitrate - 0 to 5. water change - every 2 weeks once, 10% change water topup every week due to evaporation feeding - every day 1 pellet. total number of shrimps - 20. 7 cherry, 5 sakura, 8 tiger any help would be greatly appreciated. thanks. |

Did you test for ammonia and nitrite?
Any pH, KH/GH readings? Any other creatures in the tank? How long did you cycle the tank before the shrimps were introduced? Its not normal for shrimps to be dropping so fast |

Most likely is due to your water parameters slightly off, that's why the shrimps start to die off one by one.
It would be good, that you try, taking a few picture of your tank to let us understand the exact things inside. Also, what type of food you feed to them and how much? Lastly, I'll suggest a 20% water change every week for now until things stabilize and make sure when u change water.. it does not affect your soil and etc. |
