Description: want your fish to be happy and healthy? Know the things to watch out for in aquarium fish.


Unlike what many people say, fish are not easy pets to have. They may need less maintenance than cats or dogs, but they still need specific treatments. There are things to watch out for in aquarium fish, from water-related problems to behavior problems and even disease. Use this guide to determine if there are problems with these fish.


Do Your Fish Have Disease?

Diseases such as fin rot, ich, or dropsy are common among fish. Early detection is important to treat them properly. However, fish owners often don’t find out about their fish condition until too late. Make sure you notice if your fish show these signs:


  • There are white spots, sores, or strange bumps on their skins, gills, or mouths
  • They scratch themselves on their aquarium side, driftwood, or ornaments
  • Their eyes look swollen and/or reddened
  • Their fins look frayed, damaged, or clumped together
  • They become lethargic and have no appetite
  • Their bellies look swollen or hollow
  • Their scales look different than usual (bleeding, raised, or lost their luster)
  • They have trouble swimming normally (usually a symptom of swim bladder disease)


Once you see these symptoms, you can meet a professional, such as fish store owners. Explain the symptoms or take the pictures of your fish from outside the aquarium. You will get explanations about diagnosis and proper treatments.


Are Your Fish Stressed (or Depressed)?

Fish can feel stress or depressed if their living condition is not ideal. They may lose their appetite, hide often, or become aggressive and attack other fish. There are several reasons why fish get stressed, such as:


  • Overpopulation or underpopulation

An overpopulated aquarium can make the fish stressed. They may show aggressive behaviors in response and hurt other fish. On the contrary, schooling fish may get stressed if you only put one (or too few) of them in the aquarium.


  • The imbalance between males and females

Imbalanced numbers between male and female fish can lead to aggression in mating seasons. Make sure you know the recommended gender balance of each species.


  • Wrong fish combination

Combining large, aggressive fish with smaller, gentler ones can cause stress on the small fish. Determine your fish options before choosing the best combination to put in the aquarium.


  • Improper water condition

Improper water condition will cause your fish to get stressed and even sick. Lack of aquatic plants, too acidic or contaminated water, algae problem, and muddy water can cause the fish to get stressed, sick, and even die. Make sure you check the filter condition and use water tester kit.


Knowing about common things to watch out for in aquarium fish can help you detect problems. You can also have happy fish for long years to come.
