1000 Ways to Kill a Fish volume 1

  • We are currently upgrading MFK. thanks! -neo
I have:

-forgot to plug in heaters
-forgot to turn off heaters
-forgot dechlorinator
-overfilled tank during wc
-overdrained tank during wc
-failed to quarantine
-failed to properly identify pathogen
-overdosed medication
-used wrong medication
-introduced incompatible tankmates
-failed to provide proper diet.
-dropped lights into tank
-failed to provide proper size tank
-failed to maintain healthy water quality.

All of these have resulted in a fatality for me at some point in time. Couldn't help but get down on myself when trying to think of this list, but I would still say I'm a better keeper now than I have been in the past at least.

I was going to say, "well it could have been worse", but on reflection, I don't think it could! Unless they were all in the same day!!!! That would go down as a bad day at the office, lol.
 
Forgot to close the lid on my fahaka’s tank and left a cube of bloodworms on the edge. Found him on the ground the next morning. Went and bought a new one the next day and when I was taking him out of the truck, his bag was quite light and had poked a hole in it and he had maybe 3 times his body size of water left in the bag. Rushed him inside to the tank. If I had killed a second puffer in 2 days there wasn’t going to be a third.

Not having completely sealed tops on my bichir tank almost cost me a fish twice. Now they’re duct taped in place and holes near tubes and lines covered right up. No more chances.
 
What are some causes of fishies breathing heavily??? I mean besides temp wise.

Man, this could be its own thread, even a sticky. My experience?:

Insufficient aeration/agitation/flow, I.E.: O2;
Adding a fantastic stone that turned out to be insufficiently cured concrete;
$#@!! SOB(s?) pouring beer in the tank;
Toxic plant cuttings resting in fish-storage tank (see above);
Hellgrammite tail came through & wrecked gills;
Ich;
Chlorine (spike) in public water;
Laziness in water-change schedule;
Freek-out with light or net resulting in stress and/or head-bonk into glass/decor;
etc...

So most are water-quality, some are stupidity & some are simply bad luck.
Some fatal, some not, some an indicator of something amiss & motivator to get off backside & set-right.

I’ve had two bichirs wiggle their way out of a window mesh screen that had a small slice on the frame for feeding etc, incredibly frustrating...
 
Re. jump-through gaps: Hot-Glue is brilliant stuff. Not terribly good at sticking to glass or un-roughened surfaces, but otherwise versatile, cheap & not toxic to fish (that I've experienced). Fantastic for gaps around hoses, loosens with a bit of kettle water. Can even make a mesh in situ like a hand-held 3D printer. Electric glue-gun, so be careful using above water - rubber-gloves and/or boots may be advisable.

UV-cure poly or epoxy resins are also good. Use a UV-torch to cure & it only takes a second, which means you can control timing to pull mosquito netting tight into exactly where you want it. It heats-up in curing, so watch where your fingers and/or spills are. Also not great sticking to glass, but give it a try - doesn't need that much roughness.

I keep american eel & silver arowana: One is super-sneaky, the other carries a punch. Touch-wood, we've not had a crusty-floor mortality in a few years... touch/knock wood.
 
Had a red belly piranha that was king of the tank one day and dead without a scratch on him the next. I didn’t do anything differently, nothing got in. He was right by the wall of the glass. My theory is the leporinus (who I thought was a goner) bit him in the back and he bolted headfirst into the wall, killing him instantly.
 
My biggest fail was adding fish to a non cycled tank. My convicts turned white and just looked like death. Ended up getting them back into a bigger tank and within days they've got their color back and are active again.

Learning how important it is to have a tank cycled is THE one most important part of fish keeping, imo.
