Well, we've not purchased any more fish or critters. We're kind of holding out 'til we can upgrade our lighting.
However, over the past two weeks, we've lost three of our chromis. One, who we'd named Fridge, was really the "runt" of the "litter." He was never quite right, and never recovered after I found him wrapped around the powerhead intake grate.
The second one that just kind of up and disappeare (I blame the nassarius snails) was kind of scraggly, too.
The third happened last night, right after I fed a half a frozen cube of plankton. The food was thawed thoroughly, and poured into the tank.
Seconds later, one of the chromis was flailing around uncontrollably. Nightmare said it looked like the fish had gone into shock and asked if I was sure I thawed the food completely, and I was and still am.
Water parameters are great, though I need to find a tester that includes phosphates, because we're having a spot of trouble with cyano
. But we use treated tap water, so I'm pretty sure that's the culprit. Vacuuming will have to do 'til we can get an RODI
So, I'm all bummed, and now I'm afraid to add anything new to the tank. The remaining chromis seem fine, as do the other fish and inverts we have. I'm hoping it's just coincidence that the three happened to go so close together, but I can't help but be worried about it.
