I'm looking for some advice...I used to do fish a lot when I was younger, but my father passed away and he was the one who knew everything about fish and such.
My boyfriends roommate left his fish behind, so when I moved in I took care of them. I have two 10 gallon tanks. Mysteriously two guppies died in one tank, which left behind 2 plecostomus and 1 Eel. Everything was fine, so a month ago I bought two Gourami - Blue from the petstore I now work at. They lost their color, and one died. I didn't think much of it, but soon the other had a white film on it, and soon all of the fish were dead and had the white grime on them.
So my boyfriend poured bleech into the tank after I removed the bodies, and I haven't gotten to it until now...a week later.
I'm soaking the rocks in hot water and washing everything. I'm wondering if I'm going about this right? Should I clean everything with hot water and set it all up again? I'm not sure what a cycle is...I know that some bacteria is good for the fish. I just don't want the sickness my last fish had to remain in the tank and it's rocks/plants.
Any help is appreciated. Even if you tell me I should toss it all lol.
