Cloud mountain minnows are omnivorous creatures and can survive on anything from flies and mosquito larvae, other insects, algae and plant matter to fish flakes, boiled vegetables or frozen bloodworms.



Under ideal conditions, a common goldfish can reach seven inches. Some people keep larger varieties known as “Goldie,” which can grow to 15 inches long.

Goldfish have mouths designed to accommodate small tropical fish such as minnows. Goldfish may even feed on other aquatic life being raised together, including their own parents!

Minnows can defend themselves from Goldfish by hiding among rocks and decorations of their tank, plants, or under a lid. A larger tank provides them with more room to escape or avoid larger fish predators that prey upon them.

Minnows can eat flakes as well, though it is advised to blanch them first before giving to them. Minnows thrive on diets rich in spirulina, worms, bloodworms and daphnia; in their native habitat they also snack happily on insects!


When keeping goldfish in an aquarium, it is crucial that their environment mimics their natural habitat as this will ensure a long and healthy life in captivity. One effective method to do this is providing them with sandy tank bottom and plenty of structure – this allows them to explore and dig for food while stimulating growth of beneficial bacteria.

Goldfish should avoid tank mates that can fit inside its mouth, such as tropical fish and some invertebrates. Also avoid species with spines which could become trapped between its gill plate and goldfish’s digestive tract if eaten.

Goldfish make great additions to any aquarium, providing hours of entertainment for their pet owners. However, it is important to remember that goldfish form part of the food chain and can pose dangers for larger fish at higher levels – therefore it is vitally important not to release goldfish into the wild.


Goldfish are voracious eaters and will consume almost anything they come into contact with, from minnows and plants to even their own waste! Unfortunately, minnows have no way of protecting themselves against goldfish; all they can do is swim fast or hide under tank structures to escape being eaten alive! For this reason, keeping minnows and goldfish together in one large tank – such as 55+ gallon aquarium or even pond – is recommended.

Goldfish fish can eat just about any type of food and usually suffice with just flake food from pet stores or pellets from an aquarium store, but for something a bit more nutritional you could try adding in frozen bloodworms, mosquito larvae or blanched veggies such as cucumber or tubifex as part of their daily feeding schedule – as doing otherwise could become unhealthy. Avoid feeding breadcrumbs because this can swell up and lead to internal infections in their system.


Goldfish are predatory fish, meaning that they feed on anything that fits in their mouths, including plants, food, substrate and even other fish. Therefore, it is not advised to house goldfish and minnows together as minnows form part of the food chain and will likely become targets of an energetic goldfish.

If you decide to keep minnows with goldfish, be sure they have plenty of places where they can hide from attacks by the goldfish. Also adding a sand substrate may encourage foraging activities and help minimise aggression between the species.

Rosy red minnows make excellent tankmates for goldfish. Omnivorous in nature, these fish will consume almost anything you throw their way, such as daphnia, shrimp, bloodworms, flakes or blanched vegetables like cucumber. Just be sure not to overfeed them! Remember they only require 2-3 minutes’ feedings before becoming overfed!
