Hey guys. I bought 2 dozen feeder guppies for my vacant 10 gallon tank to quarenteen for my future armatus. It seems that they are like the hardest fish to keep. i've kept bichirs, wolffish and angel fish and i can't keep guppie!!! My feeders just keep dying by small number very day. When i net them out, they have this disguisting fussy stuff on them and they are half rotting away!! Is this the cause of fungis or bacteria?? I put pimafix and salt in my tank right right. I just started to put the heat today (I got the guppies on wedsday) because the LPS guy said they don't need heaters. I think the problem of the guppy death would be no proper heating or my messed up filter. I just took my filter from my cellar and I cleaned it thoughly. The thing is, when I turned it on, black flakes splewed out and my water turn a slight grey murky colour. What happened?? I just washed my filter again with hot water and changed 50% of the water. After an hour, I saw that another guppy has died!!
Is it stress this time??
What should I do???
