Kevinnnm Posted August 31, 2022 Share Posted August 31, 2022 Hello, I have a 13 gallon tank that recently had some algae problems, and has a lot of hermit crabs. Every time I wake up for the past 3 days, there is one fish dead, that is swarmed with hermit crabs. The water is in good condition. What could be killing my fish? Water conditions: ammonia: 0 phosphate : 0 magnesium: 1350 kH: 7 Quote Link to comment
