I dont know how he died all i know is that i woke up to a dead betta in the gravel.
Im still crying
Looks like he died from brown blood sickness. Because after put in his new tank 2 days later witch was yesterday night i saw his gills were tan i couldnt do anything because it was about 11:00PM
I am so very sorry ! Just makes me think how grateful we should for each day we have and to be happy for what we have because we never know what tomorrow may bring. Rex was a great fish I know how heartbroken you must be and again I am so sorry.
