Before you know it, the snails in your tank might outnumber your fish and they can become an unsightly nuisance.

Bettas are often marketed as suitable for tiny unfiltered bowls and vases, which they’re unfortunately not. However, that does not mean they’re not a great choice for small setups. Heated, filtered aquariums of at least 5 gallons (20L) make a great single-fish setup for Betta splendens. They naturally occur in waters with dense vegetation, so consider live plants to imitate the natural habitat and provide your betta with a place to hide.The stone catfish is very peaceful and will do well with nearly every micro species on this list. It can be housed alone, but will do better in small groups. The stone catfish would do best in an aquarium with plenty of hiding place, softer substrate, driftwood or almond leaves. Water quality is imperative to this tiny fish and must be kept stable, clean, and well oxygenated. The stone catfish is nocturnal so it’s best to feed after the tank lights go out.
