I had started to cycle my tank fishless then got two blue damsels to finish it. Now they are both dead. my water peramiters are as follows
These all are acceptable according to "the contientious marine aquarist"
One reason may be oxygenation, I blocked the air intake, because I couldn't see the fish. could this be. They were both red. when I bought them they were white and yellow. IDK. Also they werent floating they were sitting on the sand bed. is this normal. Please help so I don't make the same mistake. Also the brown alge I think are diatoms are turning like a neon green. really bright
