Bala shark hit glass and died

[mike37909]

I was refilling my 220 during a water change and bala shark launched into the lid. I thought something fell at first it was loud. Went belly up instantly. I figured it knocked itself out and i held it in front of pump to revive it. Never moved just a few twitches.
No obvious damage to its head ? Anyone ever heard or seen anything like it? All my other fish are perfectly normal.

Now that i think about it i have heard of bala sharks hitting the glass so hard they break the tank. I suppose if they are capable of that they will surely knock their brains loose and die if they get spooked.

That's a real shame, that was a nice fish.

I've lost a few fish from faceplanting into the side of a tank, to include a tigerfish once.

Probably a year and a half since i got him. He recently started growing faster when i got rid of an oscar and green terror.

Bugger.

His eye does look a bit bulgey, but hard to tell if that's the way it looked before.

 

[mike37909]

Yeah I noticed that but then i looked and they were both the same size so I dismissed it. I was wondering if it had popeye. I cant say if they were like that before the impact.

Was the water filling the tank close to or the same as the tanks original temperature? I had a fish do the same thing before and after I filled the tank I realized the new water was about 5 degrees warmer than i usually keep it and it probably went into shock.

 

[mike37909]

Temperature was within a degree
I did a large like 75 percent water change but i always do that. This is the first water change since i added black sand. I believe the sand is inert so i doubt the PH was changed by sand. I guess it got scared when i was working on tank and bashed his head too hard.
