Freshwater Fish - Most Common
In this portion of the site I'm going to ask you a few questions that will help knock out 80% of the most common problems with aquarium fish.
Check for dead animals in the tank. If you find one, remove it immediately and inspect it carefully for signs of illness.
Dead fish can be caused by any number of things. Continue reading.
Check the tank temperature. Heat can kill fish in a hurry. Sudden changes in temperature - especially cooling - can prompt an infection.
Make sure your water temp is at a good number. Usually 72-80 degrees for most fish is adaquate.
Test your Water
Check your water parameters, you should do that on a regular basis. Check ammonia and nitrite levels, as well as pH levels. Also smell the water. It should have a nice earthy smell. Water quality is the culprit in many fish illnesses. Low pH and ammonia or nitrite poisoning will cause dark coloring in fish, an increase in skin mucus, erratic swimming and gasping for air.
Check the pumps and tubing. Ensure that aeration is adequate. Make sure all filters are working properly. Filters can get clogged. Be sure the filter media is clean and doesn't need to be replaced. Cloudy water is a sure sign that there's a problem.
Feeding your Fish
Have you been feeding your fish a varied diet, regularly and not overfeeding? Very hungry fish will take bites of other fish in the tank. Also beware of overfeeding, which can change ammonia and nitrite levels radically.
Is your fish eating?
Watch for fish with poor appetites. This can be a sign of stress & diseason. It can also be caused by a number of problems, dominant fish, a new environment, a parasitic infection, inappropriate feeding, etc.
Read Streaking, Gills
Check to see if the fish has red streaking on skin or bleeding gills, and note whether a fish is gasping for air at the surface. In these situations, suspect ammonia poisoning, which has no cure. It's common in new and full tanks and causes permanent damage to the gills.
Fish Acting Weird
Watch your fish for abnormal behavior such as odd swimming patterns, refusing to eat, hiding more than usual, sluggishness or extreme aggression.
Rubbing Fish on Ornaments
Look for rubbing, flashing or jittery swimming in normally sedate fish, which usually idicates skin parasites.
Fish Swimming Weirdly
Check for head standing, lying flat, floating upside down or sideways and poorly coordinated swimming. These are symptoms of either a swim bladder infection or an intestinal obstruction. These problems are caused by overfeeding or by eating dry food too quickly.
Fish Color Changes
Check for darker coloration in fish, which can indicate chemical imbalances in the water, parasites or bacterial infections.
Bloated Belly Fish
Look at your fish for an abnormal size belly, white fungus on body, fins or mouth.
