Goldfish are omnivores meaning they will eat plants as well as small insects. This means the goldfish will eat the algae that are growing in your pond, but that might not be the best thing for your pond. Adding fish to a pond, scientist agrees it is the best way to keep algae from taking over your pond.
What Kind of Fish Can I Put Into My Koi Pond?
- Goldfish. First up, the ever-popular goldfish.
- Exotic Goldfish. Telescopes, lionheads, orandas, black moors, and Ryukins fall into this category.
- Shubunkins. These fish can get up to 14 inches long in an 180-gallon pond or bigger.
- Sarasas.
- Orfes.
- Catfish.
Many types of fish eat algae occasionally, particularly string algae. Guppies are fond of string algae, but they don't do well in winter ponds. Goldfish and koi eat string algae as well, but they prefer other foods. These fish eat algae during the winter months when the pond is frozen.
Yes!
Goldfish are omnivores (they will eat both plants and animals) and they will eat – or at least try to eat – almost anything. This means that goldfish will eat algae wherever they find it – off the sides of your tank, off decorations and plants, and off the gravel on the bottom of your tank.Feeding Koi and Fish. Fish are a popular addition to the pond, they help ad life, color and personality to your water feature. Fish, such as Koi will eat certain algae and help keep it under control. Fish will also eat mosquito larvae and insects that are out of reach of the skimmer.
- Goldfish and Koi will often EAT String Algae. Especially larger koi over 12 inches.
Koi (aka Nishikigoi)
A koi fish's ability to help eat algae often is overlooked as a benefit. Algae is not the favorite food of koi, but in the absence of other (tastier) food, koi will eat algae and plants as part of their diet; especially during winter months as food is more scarce."No" to Multiple Plecos Together
They often do wonderfully alongside other types of community freshwater fish. When plecos reach maturity, they simply cannot get along with fellow plecos. They can be highly territorial around each other. Therefore, it can be extremely dangerous ever to house them together.No, not really. Like Bunji said, they'll do ok so long as it's in a coldwater tank. That means a tank that doesn't have a heater, but is indoors. The water will always be at room temperature, (about 72F), which isn't too cold for a plec.
If your pond doesn't have a significant algae issue and you're looking for smaller, attractive fish, mollies and guppies are a good choice. Like koi and goldfish, algae is not their main diet but they will eat soft green algae off of your pond liner, rocks, plants, and other substrates.
He then said to me that I should be fine with a small (1 - 1 1/2") common pleco since it will take 10 years to get to full size, or 5+ years to get to a size too large for my 29 gallon.
Plecostomus Water Requirements
A pH between 7.0 and 8.0, alkalinity between 3° and 10° dKH (54ppm to 180ppm), and temperature between 74° and 80° F will suffice for most captive bred species. If the aquarium is kept in a room below 74°, use an Aqueon aquarium heater to increase the heat.Most fish aquariums are “tropical setups” in the water temperatures of 72-84 F range. Plecos will do just fine in that and even lower temps. Even down in the mid 60 degrees Fahrenheit.
This fish is also available as an Albino Pleco. In the wild these fish gets up to 24 inches (60 cm) in length, though they seldom exceed 12 - 15" (30.5 - 38 cm) in the aquarium. They are fast growing, and have an average lifespan of 10 - 15 years in captivity. In the wild they can live more than 15 years.
Unfortunately with some fish, if they can fit it in their mouth, they'll eat it. How big is that tank by the way? You need to get the koi into a pond asap. Koi need at least 500-1000 gallons for each fish.
Use natural methods like barley straw, plants, and biofilters to keep your pond clean. Ultraviolet clarifiers, pond treatments, and gypsum are also useful for keeping the water clean and clear. Finally, empty the pond at least once a year by removing all plants, water, and fish before refilling it.
CATFISH IN YOUR BACKYARD POND. Catfish, although scavengers, will not do anything to actually help keep your koi pond water garden clean; and may actually have a greater impact on lowering the overall water quality of your pond than your traditional koi and goldfish will!
Follow our 7 tips below to help keep your pond water clean!
- Maintain a healthy fish population.
- Don't over-feed your fish.

- Choose proper filtration for your pond.
Pond Fish: The 10 Best Fish For Your Backyard Pond
- Grass Carp. Grass carp are large, cigar-shaped herbivorous fish that are perfect for rooted weed and algae control!
- Fathead minnow. These tiny pond fish have small raised bodies which can be between 2 and 3 inches in length.
- Golden rudd.
- Golden tench.
- Goldfish.

Treat the pond water with algaecides.
If you can't clean your water and remove your algae any other way, you can use algaecides to treat the water and kill the algae. Purchase an algaecide or herbicide that contains copper and spray it over your pond to begin killing off the algae.Spray, roll or brush on the waterproofing product. Allow the recommended drying time between coats. Apply two coats, or the manufacturer's recommended number of coats. Pay attention to the manufacturer's recommendation for coat thickness to obtain the recommended mileage of your finished product.
To Summarize:
- Keep the organic load down by keeping runoff out of the pond and the sludge to a minimum.
- Don't over feed or keep more fish than your pond will support.
- Install a large biological filter and give it time to work, this could take several months.
- Use enough, and the right type of, aquatic plants .
This is perhaps the simplest, long-term solution to keeping water clean and clear. Floating plants, such as lilies and lotus, provide shade and reduce direct sunlight in the pond to control the growth of algae. Add submerged plants that release oxygen to the water, such as anacharis, hornwort and parrot's feather.
Fish. Pond fish depend on pumps both to filter their excrement from the water and to keep the level of dissolved oxygen in the pond water at a suitable level. Fish may live for a short time in a small pond without a pump, but will quickly run in to problems unless the water is frequently changed.
Well fed fish can live up to 7 days without any food.
Air Gulping
Many species of plecostomus, including the common varieties can gulp air to gain better control of their buoyancy. On their way back down into the aquarium, the pleco will open its fins and sort of glide down and often emit some bubbles from its mouth.Benefits of the Plecostomus!
Sometimes called the "janitor fish" or "sucker fish" these helpful species can help keep tanks clean as they are natural scavengers. They are bottom-feeders and will eat uneaten food or other leftover matter that would otherwise cause harmful nitrates in the water.plecos do have teeth and they are very strong. infact, you can't keep certain plecos in acrylic tanks because their teeth will scratch the tank! but they won't go out of their way to attach you, so that's why not many people realize it.
In this shallow water, the movements of the fish will cause the water to circulate so it can pick up more oxygen from the water surface. The fish can survive under these shallow-water conditions for more than two days, maybe even a week or more, unless they are really crowded or not in full health to start with.
In theory, it is possible to keep fish without a filter. BUT, doing so would be a huge amount of work and expense as well. Plus, like goldfish, Plecos make a lot of waste and a lot of ammonia, which makes it that much harder to maintain the water quality and if it is not maintained, the fish will get sick.
An older, larger Pleco may need a tank size closer to 150-200 gallons. Although Plecos can be housed with a wide variety of fish, they are very territorial towards their own species. As a result, it's best to be safe and only keep one Pleco per tank.
The common Pleco, it requires a huge tank. Once they reach an adult they need at least a 150 gallon tank. As for other popular species here are their minimum tank sizes: Bristlenose Plecostomus (Ancistrus sp.): 25 gallons.
A well-balanced Algae Eater diet consists of:
- Algae and sinking algae wafers.
- Supplement with raw zucchini or cucumbers as a treat once or twice a week. Raw vegetables should be anchored near the bottom of the aquarium.
