Common threats towards aquarium fish survival

By Edited May 9, 2016 1 4

Most of the deaths of pet fish are related to complication suffered as a result of common aquarium fish disease. Fish always has a certain level of susceptibility and usually dirty water condition caused by overcrowding and poor aquarium maintenance are the main reasons why bacteria and parasites have the chance to propagate and infect the fish. Introduction of contaminated live foods is also another factor whereby harmful pathogens were allowed to enter the aquarium system and it's not common to see whole batch of fish completely wiped out with outbreak of disease.

Few of the most prevalent fish disease are ich, parasites attack, fungus infection, pop-eye and growth of tumors. Some of these can be easily cured with salt baths but there are some, which require follow-up treatments with proper use of antibiotics. As with all common diseases, usually symptoms may not appear during the initial stage and therefore, it is advisable that once you notice the fish exhibits abnormal behavior, proper treatment should be administered. Some of unusual behavior and conditions such as clamped fins, slow responses, visible body sores should trigger an alarm for you to take actions immediately. Knowing the type of disease the fish is suffering from is very important because sometimes, wrong interpretation can lead to wrong treatment being administered. Let's look at some of the common threats known as pop-eye and tumors.

Pop-eye is a condition whereby the fish's eye will actually come off from the socket. Upon close observation, what you can see is actually accumulation of a bag of fluid that is causing the eye to protrude out. Although it may not be life threatening, usually the protruding eye can cause the fish to have poor vision and sometimes it can be caught between aquarium décor resulting in grave injury. First thing first in order to address this issue, is to isolate the affected fish to a hospital tank. Increase the water salinity to 0.3% using aquarium salt and observe its condition for at least a week. During treatment, ensure that regular water changes are being carried out and after the period, if things do not improve, immediately seek veterinary help.

Tumors can also be harmful and so far, there is scientific evidence that points to the disease actually caused of parasite infection. Usually fish that suffers from tumors will have visible lumps that appear as swelling of the internal organs. One of the most commonly seen conditions related to this is "kidney bloat" and as far as I'm aware of, there is no effective form of treatment for this and it's best that the owner should seek veterinary help. Hopefully with early detection, there is chance for the condition to improve and for the fish to heal completely.

My fish had a pop-eye. The medication we used didn't work fast enough. It eventually died.

I'm not much of an aquarium guy, but you explained these common threats to aquarium fish - and how to treat them - so well that I'm half tempted to go get one and stock it full of awesome fish.
