Question

Answer 1

Your questions are difficult to answer specifically without knowing what kind of fish you have and without more detail on the black "spots". There are species of fish that actually prefer to live in different levels of the tank, with some swimming mostly at the bottom, middle or top of the tank. Also, each fish has its own personality and preference. I have several goldfish living in a 75 gallon indoor pond. One is very shy and keeps towards the bottom of the pond and under some plants, whereas most of the other fish swim around more. One fish is very bold and even takes shrimp pellets from my fingers. They have always had these personalities. As for the spots, some fish develop colors and patterns as they age... this could just be a normal color pattern. However, I am sending you a link on possible problems - one on black spots in particular. Good luck and enjoy your fish! http://www.goldfishinfo.com/ailment1.htm#blackspot

The water you're determining to purchase, is it opposite Osmosis filtered? If thats the case it will be causing issues. The water has been filtered to get rid of all the dissolved solids, along with the mineral buffers that help keep the pH secure. So the organic organic and organic action contained in the tank will right away drop the pH. then you fairly have added an Alkaline buffer and it has by wonder swung back to a intense pH. No ask your self the fish are turning out to be slightly less than pressure. attempt your faucet water back and confirm you take advantage of a water conditioner and it will be positive. in case your faucet water is amazingly demanding and intense pH then you fairly might want to blend it with the R/O filtered water and get something smart on your fish. also - really than annoying too a lot about pH, what are the different water parameters? Ammonia, nitrite and nitrate might want to be all out of wack in a sparkling tank and are a lot extra in all probability to reason issues than a touch incorrect pH. Ian

Is this fish also a goldfish? Large black patches could be the sign of a healing ammonia burn. If these are small dots, it's probably the larvae of a type of parasite http://www.fishdeals.com/fish_diseases/black_spot/ These don't hurt the fish unless there are a lot of them on one individual.

Either one of these could cause the fish to be at the bottom of the tank, as well as their body shape if the fish are fancy goldfish. The egg-shaped bodies and double tails don't allow them to swim as quickly or efficiently as other fish, so they may need to take a "breather" if your filter current is too strong for them. See this link for other reasons they may be on the bottom: http://www.goldfishconnection.com/articles/details.php?articleId=145&parentId=12

Answer 4

The black spots could mean your fish has a fungal infection.
Try looking it up on Google. But he's probably sick, that's why he stays towards the bottom of the tank.
You should talk to your veterinarian if he doesn't get better.

Answer 5

Check the temp...heat rises so its probably cooler at the bottom of the tank.

It could be the water temperature. Water is cooler on the bottom.
