big mistake

last night i changed the substrate in my 5.5 and cleaned all the decorations. i have no idea what i did wrong but it led to 4 mini cories dying.

i sprayed the plants with excel to try and kill the algae the algae did die along with my fish

i still have one otto in there and 2 guppy fry. i did a 20% water change and hopefully that will work

You may have knocked out all of the biological bacteria that were keeping the tank cycled and it may have started a mini cycle which may have raised the ammonia and such. Ive read that corys are normally pretty sensitive so that could have led to the deaths.

+1
I have also found C pygmaeus are pretty sensitive to excess Excel dosing. I am assuming what you are referring to C pygmaeus as mini Cory.

I doubt it was caused by an ammonia spike in that short amount of time.
Did you drain the tank to remove the substrate?

you might have had some nasty pockets of amonia, or other chemicals, and or bacterium that was released when you shifted around the substrate. These can be particularly lethal if you arent carful.
