Tropical Fish Compatibility Chart

When you are new to the hobby of aquarium keeping it can get very confusing to figure out which fish species are compatible. Therefore a tropical fish compatibility chart can be very handy.

The tropical fish compatibility chart shows you which freshwater fish and freshwater plants are compatible with each other. However you also need to consider pH levels, gender, feeding requirements, water temperature, size, and several other factors.

To ensure you have a healthy and thriving aquarium it is important to consider the compatibility of your fish friends because if you just add random fish in your aquarium, it is basically waiting for a disaster to happen.

When you add random fish in your aquarium it is very unhealthy. Your fish friends will not only become stressed but some of your fish can turn aggressive and will bully your other fish. Which can cause your fish friends to get sick or die therefore you need to watch out for signs like.

  • Pale skin
  • Hiding all the time
  • Missing pieces from their tail
  • Visible injuries
  • Fish chasing each other
  • Swimming strange
  • Not eating

When you observe the behavior of your fish friends it will make it easier to spot signs of stress or bullying from other fish.
