Although you can keep dwarf shrimp with dwarf crayfish in large tanks with lots of hiding spaces, the shrimp always feel stressed out in such tanks as the crays are quite aggressive towards anything that "lands" right in front of them...such as shrimp.Kenshin wrote:1. NEVER put Cambarellus patzcuarensis (orange dwarf crayfish) or any sort of dwarf crayfish in the same tank with your shrimps. I was literally shocked that even after I fed the crayfish well, they were still hunting for food and I saw 1 crayfish ate 1 or 2 green shrimps
2. Never take out all of the Najas plants out all at one time like Mustafa and everyone has stated.
Yes, that's a big mistake. You have to reduce the plants little by little. Every few days take a little clump out. This way the nitrifying bacteria will have time to grow and take care of the ammonia.
