Hi there, I have a 15gal Fluval Flex with Fluval stratum substrate. I have a bunch of nice plants, 3 tetra cardinals, 2 glofish, 3 julii corydoras, 4 ghost shrimp and 3 nerite snails. All fish are young and small. I change my water (50%) weekly. And feed once per day and a 1/4 algae wafer every 2-3 days for the corys and the shrimp.
Over the last couple days, one shrimp wheat missing, another turned white and today the big one died. I checked all water parameters and all levels are really good. I use a GH
supplement as well to boost the minerals.
Any idea what could be the culprit.
