A decrease in goldfish's respiratory rate would be caused by one of two things. The first would be that the dissolved oxygen levels increased somehow and now the fish does not have to breath as fast to get the same amount of oxygen. The second reason would be because the water, it is in, experienced a cool down in temperature- this can sometimes instinctively cause a fish to go into a kind of hibernation where it slows down it's bodily functions (including breathing) until the water returns to normal.
Death and migration are factors that can decrease hare population.
Possible reasons for a bump on a goldfish's head could include injury, infection, or a tumor. It is important to monitor the bump and consult a veterinarian for proper diagnosis and treatment.
there are many reasons a population or organisms would increase or decrease. some reasons are diseases, predator increase/decrease, good/bad weather, and enough/not enough resource's. :) yep
Immigration, decrease in infant mortality, increase in birth rate, decrease in mortality.
NO! Discus are very fragile fish- very sensitive Goldfish are messy plus, goldfish like temps in the 60's and discus like them in the 80's i can think of millions of other reasons do discus a favor and never keep them
Possible reasons for a goldfish to have bubbles on its head could include a swim bladder disorder, poor water quality, or excessive gas production in the digestive system. It is important to monitor the fish's behavior and consult a veterinarian for proper diagnosis and treatment.
Goldfish can die overnight due to various reasons, such as poor water quality, inadequate oxygen levels, sudden changes in temperature, or diseases. It is important to regularly monitor the water conditions and provide proper care to prevent sudden deaths in goldfish.
maybe because they are getting smaller
There are biological reasons for the occurence of death
The main reasons for this decrease included an increased use of computers, foreign competition, increased productivity, reduced corporate spending, and U.S. demographic changes.
Well, most people think it just got it but there are many reasons. One of them is that maybe the goldfish got hurt like a human does. Another way is that it was born like that.
There are several reasons why your goldfish may not be eating. It could be due to stress, poor water quality, illness, or overfeeding. It is important to monitor their environment and behavior to determine the cause and take appropriate action to address it.
