Top Pros and Cons - Benefits of Community Aquarium / Fish Tank:

Community aquariums are more eye gazing because they have different species of fish having different shapes & colors. Different types of fish love to mix up & swim together. Community aquariums usually stock many fish so their nature could be different. It is hard to keep different species of fish together because they could show aggression especially in small community aquariums or when they are stressed. Fish can also form their own territories, & potentially stop other fish from entering their territory. Community tanks have many benefits, & several drawbacks too that I have discussed in this article.

Disadvantages / Cons of Community Fish Tank:

Check out main cons of community fish tank:

  • Territorial fish form their own territories in community aquariums so they could be aggressive towards their own kind & other species of fish.
  • Different species of fish need their own water parameters such as PH, Temperature & Water Hardness so choosing right tank mates could be difficult.
  • Large fish tend to eat small ones. Fin nippers could nip the large flowing fins of certain fish so learning about the behavior of every species that you want to keep in a community tank could be time consuming.
  • Fish creates too much waste in the aquarium due to their large numbers so they need a single large or multiple small filters.
  • Fast flowing water from the filter or powerheads could affect some fish including the small ones.
  • Fish could breed & give birth to babies in the community tanks so fries are prone to many predators. It is advisable to keep many plants, decorations & other structures that offer lots of hiding spots to the stressed fish & fries.
  • When food is served, active fish eat all of them before passive fish have the chance to spot food. Some fish like to swim in the bottom levels of the aquarium so it is hard to feed them in the community aquarium because they rarely come up for eating. It is advisable to feed them pellets or food that sink to the bottom.
  • Some fish swim quickly & could stress others. It is hard to find fish of the same nature.
  • Some fish prefer bright tank lights while others are happy in the darkness. Also, live plants have varying needs for artificial lights.
