The bodyshape of the Siamese Algae Eater is elongated and a little bit similar to the bodyshape of a shark. The Siamese Algae Eater has a black line in the middle of their body. And the rest of the body looks golden. That all makes the Siamese Algae Eater a very attractive fish.

Algae Eating Black Japanese Trapdoor Pond Snails are the preferred species of snail for recreational and professional pond and water gardeners world-wide. Japanese Trapdoor Snails are one of the few snail varieties that can over-winter well and survive in harsher northern climates. Japanese Trapdoor Snails are a great asset in helping keep algae under control in your pond and water garden as they groom plants, planting-pots and water garden rocks and walls. Japanese Trapdoor Snails will tend to the ponds bottom, consuming any decaying matter such as leaves, excess fish food, and even fish waste.

Black Japanese Trapdoor algae eating snails are live-bearing; they only breed a couple of times a year and will not take over your pond like other nuisance egg bearing snails can and will. In order for your algae eating snails to have a positive effect on algae growth, a minimum of 10 snails per 50 sq feet will be needed, and farm ponds will need to have at least 200 pond snails to have any positive effect at all. The Florida Flag Fish, Black Mollies, Gold Barbs and Rosie Barbs will all eat hair/thread algae

Do not be confused with Flying Fox which looks similar but with different characteristicswhich makes them less desirable for your community tanks. SAEs are peaceful and are goodalgae eaters. They grow up to 6 inches so you will need a decent sized tank - at least 30x12inch footprint. Once they hit around 4 inches, they will not eat algae as well. Most storeswill sell them at 2 inches in size, so if you are looking for a long term solution, this maynot work for you. They will eat variety of algaes but I have never seen them eat long strandsof hair algae. If they are hungry, they will eat black beard algae. They are often suggestedas a schooling fish, and if you have more than one, they often swim together. But unlike mostschooling fishes, SAE can be kept in singles.Otos are very peaceful and stays small (2 inches). They do a great job in eating algae butunfortunately only really soft early form of algae. Diatoms (brown) are one of their favoritemeals. If your tank is infested with hair or black beard algae, do not buy this fish to cleanthose - Otos don't touch those algaes. Just about every specimen in the store are wild caughtand due to the way they are caught in the wild, they are very very sensitive during the firstmonth or two. Don't be surprised if you loose a large percentage of Otos after a month. Onceyou manage to keep them alive for few months, most likely you have a healthy specimen andwill keep your tank clean for many years to come. They can be kept in a small tank such as 5g.The Siamese Algae Eater is another great algae eater. These fish are peaceful and gentle on live plants. They are between 4-6” fully grown. One of their best features is their constant appetite and willingness to eat more than just one type of algae. They are even willing to eat the awful Black Bearded Algae. Just the fact they are willing to go against this villain of the aquarium world solidifies their superhero status.Amano Shrimp. (AKA Cardina Japonica):
Now these are back in the "cute" category. Plus these are probably the hardest workers, next to the otos, I've ever seen in my tank. They are incredibly industrious and will enthusiastically go after soft green and hair algae. There is some disagreement as whether or not they also eat black brush algae. Mine do not. You do need to get quite a few of them to make a dent, as they are small (no more than 2"). They also need a nicely planted tank with places to hide. Obviously, they can't be in a tank with fish that will eat them. And they are not cheap - about $7.50 a pair in the Washington D.C. area. A final note: they are not supposed to be able to reproduce in freshwater tanks, which means you won't end up with herds of them (see CRS below.) I highly recommend these little guys.
