Minnow Troubles: Tale of the vanishing fish
So about two weeks ago I bought some White Cloud Minnows 12 to be exact. I set them up in the bare bottom, heavily planted, sponge filtered tank I was setting up for breeding betta. There is a number of plants and 3 mystery snails as well. There is an adjustable heater set at 70 and an ambiant air temp of 70-74 in the room thanks to a ceramic heater used to keep my bettas warms (Yes it works quite well many of the bettas are high 70s to 80 and the rest are mid 70s)
Now here comes the odd part of this all. At the end of the first week I have about 8 minnows that I could see on a regular basis. I figured the rest were hiding in the plants, as I could only hope for. Seems I was wrong over the course of the rest of the time till now the number has dwindled and fallen till it has come to only 2. The last two are in a new 5 gallon with 2 new mystery snails, and 3 less than inch currently albino cory cats. It is filtered. Currently ambient heated till new heater is set up.
(I am well aware the corys can not live in the tank long term)
So my question is what could be happening to my minnows?
Water temp is spot on for them, heavily planted, the snails are just fine(meaning not sick still very active)
Here is the history of the tank that I posted elsewhere before
"It used to hold toads, yes I know toxins, BUT it was unused for close to 6 months, then soaped, rinsed, bleached, rinsed, AQ salted soak and rinsed , and sat for for awhile then rinsed really really well again."
So does anyone have any ideas?
I am personally hoping it is something that is effecting only the minnows, because I personally do not want to have to restart my whole breeding tank. If I need to of course I will, I will not out my bettas or fry in danger.
