Gouramis are a popular choice for community tanks due to their peaceful nature and hardiness. They come in a variety of colors, sizes, and shapes making them an attractive addition to any tank. Gouramis make great tankmates for many other fish such as tetras, danios, corydoras catfish, rasbora species, plecos and even larger barbs or rainbowfish. However it is important to consider that gouramis can reach up to 6 inches in size depending on the species so it may not be suitable for smaller aquariums with modest stocking levels. Additionally they prefer slow-moving water with plenty of vegetation which some other fish may not appreciate as much as the gourami does. It is also recommended that you avoid keeping two males together since they can become aggressive towards each other if one becomes dominant over the other during breeding season leading to serious injuries or death. Despite these few considerations however most gourami species do extremely well in a community setting provided all its inhabitants have enough space and are compatible with each other’s particular needs!
