thanks, it seems that the 1st time isnt that harsh to me personally. i did very much enjoy his presense. while i had him alive though i didnt get as attached to a fish as much as a dog or cat which which would follow one around or go outside but he was an easy fish and gave very few health problems ie 2 finrot cases. i'll probably put him in my blue leaf (no new blue leafs anymore) poinsettia. that plants 1 year old and still going or the succulent type plant that i have.
i'll wait a month or so until the next betta a PK to restock the 5g left side. i'll need to find a PK locally first.
it kind of makes me wonder if ES salt was the right descision but it could've still happened and been a bit more complicated ie dies in 5g cycled with a VT, nerite and plants. ive let the 1g rest for 5 minutes in vinegar solution and 10 minutes with somebleach solution. hopefully its safe. i'll repeat the treatment a second time later on.
