My Albino Cory Grew Dots?

xRacheLx

Last Wed. I went to Petco and bought the last albino catfish and 5 neon tetras.

2 Neons died while I was floating the bag. The catfish looked fine. I had a betta in the aquarium at the time.

The day after, I awoke to a dead tetra. I decided I would go to Petsmart to get 2 more corys and more tetras. So i proceeded.

On Friday, I knew my betta has mouth fungus. He started to act weird

Saturday, my betta went to the big pond in the sky.

Anyways, last night, I treated my tetras and corys to Fungus Clear, if they were infected. I put the correct dose in a 1/2 tank.


That is the background history of the last week and couple days.

Anyway, today I left for church 9 o clock, came back 1-ish. I notcied that underneath one of my albino's eyes was to blue-colored dots. They were symetrical and was the color of my gravel....Should I have nay concerns?

Never mind about it. They 'dots' went away. I gues it just happened from digging in the gravel.

Common “wisdom” in books and “experienced” fish keeper tell you to float the bag with your newly arrived fish to adjust the temperature; that is the worst possible solution and nonsense that has survived forever. Well-packaged fish can survive 2-3 days in a bag with no problem. The water may be cold and a bit filthy, but the metabolism of the fish is slow now because conditions in the bag have worsened only gradually and they have adapted. When you warm up the dirty water, the metabolism kicks back in and the fish get terrified due to the light and warmth. If the bag remains closed, low oxygen levels may now lead to suffocation because the fish panic and use more oxygen. In normal fish bags (non-breather) there is also an excess of carbon dioxide (CO2), which means that the pH has dropped slowly because of continuous formation of carbonic acid (CO2 + H2O = H2CO3). However, as soon as you open the bag, the CO2 escapes quickly and the pH can rush up from <6 to 7.5 >. If there is ammonium (NH4+) present, it will quickly turn into ammonia (NH3), burning the gills, fins, and skin of your fish. The higher the temperature the faster this process becomes. - Frank

Sounds like there's a problem with your tank, too many fish are dying.

who keeps a fish tank at 6.0 ph isnt that way to acidic for most fish

Alot of people keep certain fish at a Ph lower than 6.0..............Most of your South American chacarins prefer and do much better at a very low PH...........These fish in their natural habitat are living in water that can be as low as 4.0, so an aquarium with a Ph of 6.0 is optimal for most tetras.........My 55 gallon tetra tank is at 6.2 last time i tested it and i would love to get it lower still...........My tetras have thrived and have shown better color than other people tanks who have the same fish..............Getting your water to a lower Ph is not that difficult to achieve with the use of peat in your filter and a little bit of rainwater............

@Coryologist
So what are we to do? Instantly dump the fish into the tank?

Sorry for posting a bit off-topic. I just got surprised by what I read.
