It tends to become a problem when there is more than one gourami in the aquarium. They see each other as competitors for the same territories, competitors for mates or as prospective mates. Battles can ensue. Really, the behavior is similar to that of their relative, the betta. In large aquariums, it’s less of a problem because there is more room for fish to run and hide. However, the blue gourami grows to 6 inches, so a big aquarium may not be as big as you think. I recommend at least a 29-gallon community for one small specimen of this fish. A 55-gallon (or larger) aquarium is ideal for a community containing a full-grown blue gourami. I also recommend keeping no more than one gourami species per community.

Hello M Ahsan, Your tank is pretty full with those angelfish and gouramis that are going to grow large and fairly territorial (especially the angelfish). If you would like algae-eaters, I would recommend those discussed in this blog. Not all plecos grow large – those examples in this blog stay= smaller, for example – and if you are doing regular maintenance and not overfeeding the tank, the waste from them shouldn’t be extreme. Nerite Snails also don’t reproduce rapidly in aquariums. Some loaches stay smaller as well and Otocinclus catfish like the one pictured here would be sutiable as well. Jan 7, 2017 ... Learn how to choose the best fish for your small tank and better understand the needs of your aquarium's inhabitants.

It comes with a lighted hood, a small packet of sample fish food, an undergravel filter and a small air pump. You will need to get some other items as well for your aquarium. As mentioned previously, a small tank can be more work than a large tank because you really have to stay on top of those water changes to prevent the small aquarium from becoming too polluted. Here is a list of the bare minimum things to have for any small aquarium:“The bigger the aquarium, the easier maintaining it will be.” This is probably the single most important rule in the hobby, and for someone setting up their first aquarium, it is an absolutely essential fact of life. The size of the aquarium has a direct impact on several key physical and chemical processes, including pH stability, thermal stability, and the dilution of metabolic wastes such as ammonia. The smaller the tank, the less stable and the more toxic the environment is likely to be.

The size of the aquarium is also important in terms of how fish behave. Schooling fish need to be kept in groups of at least five or six specimens, and that it turn requires a certain amount of aquarium volume and swimming space. When kept in insufficient numbers, barbs, danios and tetras become frustrated and often turn aggressive or nippy. Territorial fish need to be able to claim a certain patch of ground, and if there isn’t enough space in the tank, fighting or bullying can occur. Livebearers pose a particular set of problems because of the way males fight with each other while also tending to bully the females. It is important that there is enough space for the male and female livebearers to spread out, and if necessary find hiding places where they can rest or give birth safely.
For all practical purposes, the minimum “safe” aquarium size is 20 US gallons (75 litres). Such a tank will be big enough to accommodate a reasonable selection of small aquarium fish without being particularly large or expensive. More ambitious aquarists interested in big or territorial species such as cichlids should consider larger systems though, with tanks up to 55 US gallons (210 litres) in size providing a good balance between size and expense.
