I have noticed a few of my adult shrimp have died since being moved into a new tank, they used to share with my guppies, but theyre eating their babies so i purchased a small 18L fish tank with a built in filter, The ammonia is low, it was pretty high in the old tank due to too many fish, PH is 7.2 and temperature is 30c, other tank was 30c too where they lived for 2 months. They have been in their new tank for 2 days and i can already see at least 10 shredded skins on the floor (theres around 15 shrimp) What could be causing this? I was told on my other thread about filters that the mechanical ones are bad for shrimp so I ordered a sponge filter online I also got a air pump to attach to it, so within a week they should have that set up but i dont think that is what has killed my shrimp Here is a picture of their tank. Theres some driftwood, a boat wrapped in moss, a big ball of seaweed that is a little dirty (from their old tank to help cycle the tank) some small plants from their old tank. The bottom is NZ sand $20 a bag for 5kg so good stuff (isnt coloured) I hovered my hand over the filter and it vibrates lightly, they get 7 hrs of light a day.

Thank you everyone I have submerged both filters, and ordered a sponge filter online I also got a air pump to attach to it, so within a week they should have that set up I have noticed a few of my adult shrimp have died since being moved into this new tank, The ammonia is low, it was pretty high in the old tank due to too many fish, PH is 7.2.

Hello all I just bought a 16L BluePlanet aquarium for my Shrimp as they were really stressed with my guppies, they love the new room they have, although it small. It came with a CX200 filter with no instructions. I have added a photo of the fish tank with the filter. Am i meant to fully submerge the filter? If I do submerge it the electrical cord gets slightly covered. Its been 24 hours (with 30+shrimp) and we lost 2 (i think because the move was so stressful for them, but slightly worried about the filter) The guy at pet stock said to submerge. If i dont submerge it, the lid wont shut and it sounds like a chainsaw. Any help would be greatly appreciated.
