But my other parlor palm is doing okay- though a bit dry and pale at close inspection.
And now the sad news. Which I'm feeling rather miserable about, as it must be my fault. I lost most of my fishes yesterday. I was doing a water change, larger than usual- thirty percent when usually I do fifteen to twenty percent. I think it had been two weeks, and I know that before that I had long neglected the tank, so I thought: more clean water is better! Except it wasn't.
It started out fine- the fishes were acting perky, flitting around the siphon hose- one even got sucked into the bucket and bruised up, I put him back in the tank with regret, not sure if he'd survive that physical trauma. Last time I did a wc I had dosed some plant ferts, even though they're old and probably expired- and I was admiring how the plants look better- I hadn't noticed they were doing poorly, but now some of the crypts have redder stems, and stand up taller
-I tried to get a picture of a minnow by the crypt undulata-
Some anubias leaves had melted, and lots of vals, so I spent time cutting out the dead bits. But the green leaves still there on the vals looked healthier than before, so I think those plants were just ditching the old leaves and growing new in response to the changed conditions. Even my bolbitis fern looked greener and more upright.
Then I noticed the water line wasn't quite up to the lower edge of the rim yet, so I went in the kitchen to fill another gallon. I poured it into the tank, and things went bad immediately. The minnows started looking super stressed, bending their heads and tails up, gaping at the surface, or crashed on the bottom not moving. Only one was swimming with normal posture. Their bellies bloated white (burst swim bladders?) and then some started spinning, randomly darting into corners and running their heads into the substrate. Disoriented? Starved of oxygen? I could only think that something was bad in the water, so my immediate reaction was to do another water change in hopes of diluting whatever it was.
I changed another ten gallons. One fish died. Several of the others relaxed a bit, and the paradise fish- who'd been hiding under the bolbitis driftwood- came out to breathe at the surface. His fins clamped, but he wasn't writhing or swimming erratically like the others. I tried to figure out what went wrong. My first thought was the old ferts were gone toxic, but I'd put a bit in the shrimp bowl, and those guys were fine. And aren't shrimp more sensitive. Then I thought maybe something wrong with the tap water- the test showed very little nitrate (5ppm or less), zero nitrite but some ammonia (barely green in the tube). But again: the shrimps and snails in the bowls were fine.
Then I happened to smell my fingers. Strong sulfur odor. Realize if the prime had dripped on/from the cap, I got some on my hands. I thought I'd wiped or rinsed it off, but not good enough. And maybe I miscounted and that last gallon had an extra drop of prime in it, three instead of two. I didn't think one extra drop would matter in a thirty gallon tank. In fact I used to double dose prime in my first tank a long time ago- and while that wasn't the best thing to do, none of the fishes died suddenly like this.
Because the minnows were dying, one after the other. While Tucker hid alternately in corners and under the driftwood. However much prime was on my skin could have been extra concentrated. (I know I didn't have any sunscreen, insect repellent or lotion on my hands). The other factor is that earlier in the week we had a power outage. It lasted hours. I was about to pull out the battery-operated air pump to run the filters overnight, when it kicked back on. So I thought the tank was fine. But maybe it was out long enough that some of the good bacteria colony died off, and it hadn't recovered all the way yet? Also, I hadn't vacuumed the substrate in a long time, and a few stems got disturbed, releasing some mulm into the water column. Any one of these factors don't seem like disaster on their own, but altogether I think it's what sent my little fishes into shock. Low bacteria strength, sudden release of ammonia from the substrate, accidental overdose of dechlor . . .
The minnows all died by nightfall.
Tucker was not looking good. Every time he went up to breathe, there was an odd raspy sound. Injury to his gills? I don't know. I thought this would be my last picture of him alive.
And his color looks good.
And he's relaxed- more than I've seen in ages. I suddenly wonder if he found the minnows bothersome- all their quick activity. I'm inclined to think he's just happy to be alive, but it's probably that he finds the tank environment more calm now.
