If you've ever wondered are killifish fin nippers, here's what their behavior actually looks like and how to keep a peaceful community tank.

Yes, for most hobbyists killifish rank among the most approachable egg-laying fish you can raise at home, because a single pair often produces dozens of eggs per spawn and the parents ignore the eggs completely. The catch is that “killifish”…

Most killifish are not aggressive, but a few genera defend territory hard, and males of nearly every species can turn feisty in cramped quarters. Aphyosemion and lampeye species coexist with small community fish when given cover, while Fundulopanchax and Nothobranchius…

No. Killifish are not bottom feeders. They spend most of their feeding time hunting at the surface and in the mid-water column, striking upward at small insects, larvae, and tiny crustaceans with an upturned mouth built for that exact job.…

To answer are guppies aggressive directly: a true guppy (Poecilia reticulata) is not an aggressive fish by nature, though male guppies can chase other males, harass females relentlessly, and nip slow-finned tankmates when the setup goes wrong. Most behavior labeled…

Yes, guppies (Poecilia reticulata) are widely considered one of the easiest freshwater fish for beginners because they tolerate a wide pH range, eat a basic omnivore diet, and stay small enough to thrive in modest aquariums. The catch is that…

Gourami fish temperament runs the full spectrum, from the famously combative three spot to the shy honey gourami, and most pet-store species sit somewhere in the semi-aggressive middle. Aggression depends on species, sex, and tank setup, so two males in…

Warm, soft, slightly acidic water held rock-steady and an immune system that collapses under any nitrogen spike place German blue rams in the moderately difficult tropical fish category. A cycled 20 gallon (76 L) aquarium with stable heat between 78…

They can be, but only when the setup matches the animal. A properly housed goldfish (Carassius auratus) needs at least 20 gallons of filtered water, a varied diet, and stable water chemistry, and in return it can live 10 to…

No, they sit firmly in the mid-to-lower water column as opportunistic foragers, not dedicated substrate eaters. Their Mikrogeophagus ramirezi lineage links them to earth-eater cichlids, yet their small forward-facing mouth, lack of barbels, and laterally compressed body are built for…
