In addition, small invertebrates such as <a href=\"https:\/\/keepingcatfish.com\/cory-catfish-and-shrimp-tank-mate-guide\/\">shrimp<\/a> and <a href=\"https:\/\/keepingcatfish.com\/do-cory-catfish-eat-snails\/\">snails<\/a> are also excellent choices for tank mates.<\/p><p>Be careful when choosing tank mates that need very different water conditions. For example, some fish prefer more acidic water, while others prefer more alkaline water. Ensure all the fish in your aquarium can thrive in similar water conditions.<\/p><p>Overcrowding is also a common problem, especially in small aquariums. When we have fish in a small space, they can get stressed.\u00a0<\/p><p>Along with this, the water has more bioload produced by the fish, which helps to quickly degrade the quality of the water, further damaging the health and behavior of the fish.<\/p><p><span style=\"font-style: inherit; font-weight: inherit;\">Overcrowding can limit available space and leave fish stressed, disoriented, and with no hide.
