SO 2 days ago, I went to petco and bought a citron goby and cleaner shrimp for my 12 gallon. The next morning, the cleaner shrimp was dead, but the goby perfectly fine. So i did a water change that morning and it was cool. SO we exchanged the shrimp for a coral banded shrimp. I just woke up to find it DEAD. I put their baggy in the water for around 30 minutes, then gradually started poking small holes in the bagover about 15 minutes, then opened the bag and put them in. They seemed perfectly normal, checking out the new tank, the coral banded shrimp had to snap at one of the clowns so he would bug off. i tested the params and got strange colors as results that were not even near the charts. It's time for a new test kit. But this time, I want an electronic one. Any suggestions?
