Goldfish are generally bottom feeders that search their tank substrate for food sources. In addition, they also take food opportunities at surface and midwater levels as opportunistic feeders.
Feed them slowly sinking foods such as flakes or granules designed for goldfish or other freshwater fish to prevent them from inhaling air from the surface and upsetting their swim bladder and equilibrium. This will keep their swim bladder full while also maintaining equilibrium in their environment.

Rosy Barbs
Rosy barbs are stunning, active, peaceful species that make an excellent addition to an aquarium. Undemanding and hardy, they rarely experience serious health problems like Ich, which they could potentially acquire through secondhand equipment or entering other tanks in your tank.
These species excel at processing high levels of nitrates, making them an excellent choice for newly established tanks that have yet to complete the nitrogen cycle. Furthermore, they thrive when kept in an attractively decorated tank with plenty of plants to stimulate them and keep their brains active.
As fish tend to nibble at more delicate-leafed plants like Java fern or Hornwort, consider creating an aquarium environment with fine-grained gravel or sand substrate and water temperatures between 6-8degF warmer than their native habitat. For optimal success in keeping these creatures alive in captivity.
Platy Fish
Platy fish are thick-bodied, short-finned bottom feeders with an impressive array of colors that live at the bottom. Extremely prolific reproducers, they show numerous behavioral changes as they near gestation. It is therefore crucial that hiding places such as plants or decor are provided during this period for female fish to conceive successfully.
Fish recommended for beginning aquarists include Angelfish due to their easy care requirements and resilience under harsh conditions. They thrive in aquariums with plenty of open spaces and thrive best with plants like flowers. Angelfish feed on flake food such as flakefish or freeze dried foods as well as live brine shrimp or daphnia; oxygenating agents like air stones may provide added oxygenation benefits in their tank.
Bristlenose Plecos
Some plecostomus species can reach adulthood as large, needing ample room in their tanks. Bristlenose Plecos tend to reach no larger than five or six inches as adults.
These fish are easy to care for and make great additions to any tank, as their natural habitat lies within tropical freshwater rivers and streams – attempt to recreate that as closely as possible within your aquarium environment.
Male plecos can easily be distinguished from female plecos by the length and shape of their “bristles,” which extend from their snouts. Male bristles tend to stretch further towards the center of their heads than their counterparts on females while shorter bristles distinguish female plecos from each other.
Since hedgehogs are herbivores, provide yours with plenty of plant-based wafers and pellets. In nature, hedgehogs feed on algae as well as small insects.
Hillstream Loach
Hillstream loaches are peaceful fish that scavenge through substrate to eat leftover food particles and nibble algae, helping keep nitrate levels down in goldfish tanks. Hobbyists should provide them with hiding places and dense plant cover so as to minimize stress levels and decrease anxiety levels.
Hillstream loaches can tolerate a wide range of water temperatures, though they prefer cooler environments. They require at least 20 gallons for housing purposes and should be housed alongside similarly-sized fish to reduce risk from larger, predatory ones.
The reticulated hillstream loach (also referred to as the tiger hillstream loach or golden ring butterfly sucker) is one of the most widely sold aquarium fish species. Resembling mini-stingrays due to its streamlined body and horizontal ventral fins that enable it to grip onto surfaces, these loaches make popular choices among aquarium hobbyists.
Hoplo Catfish
Hoplo Catfish, more commonly known by their popular names Hassa or Spotted Hoplo Catfish (Megalechis thoracata), are incredibly fun and helpful aquarium fish to keep. Not only will they consume any unwanted food that accumulates, they will also support plant life by fertilizing their environment with essential phosphorous.
Hoplos enjoy living in tanks with high oxygen levels, where they can root around for food in search of sandy or fine gravel substrate. Since Hoplos are omnivorous fish, their diet should include high-quality flakes, pellets and granules alongside live and frozen foods like bloodworms, brine shrimp tubifex worms as well as blanched vegetables for optimal success.
Hoplos fish are peaceful aquarium inhabitants that should be kept in groups of six or more fish to prevent aggression from overcrowding the tank. Hoplos can co-habitate peacefully with other aquarium species like bettas, guppies, tetras, and Kuhli loach species.
