The Spotted Borneo Sucker (Gastromyzon punctulatus) is a very interesting freshwater loach that is native to Malaysian Borneo. It is known for its gray body coloration, white spots, and occasional blue highlights on its fins, its peaceful yet outgoing demeanor, and its fascinating social behavior with members of its own species. This fascinating, peaceful fish is an algae and biofilm grazer that is an excellent candidate for the mature subtropical aquarium.
An aquarium with heavy water flow (10-15x turnover per hour) and very clean, clear water is required for the Spotted Borneo Sucker. Like other hillstream loaches, this loach is native to shallow, clear, fast-flowing waters and it is sensitive to declines in water quality, so regular aquarium maintenance and maximum oxygen saturation are absolutely necessary..The Spotted Borneo Sucker is a biofilm and algae grazer in nature. It is known to usually accept frozen meaty foods, but such foods should only be fed occasionally since excess protein can be deadly to most biofilm grazers. This fish will also often accept high-quality dry foods that are rich in plant matter, but it is absolutely essential that biofilm and algae are naturally available in the aquarium to ensure its long-term health or else it may slowly starve. As long as it is kept in a well-maintained, mature aquarium with good biofilm and algae growth as well as high water flow, the Spotted Borneo Sucker is a hardy and entertaining fish. It will not bother aquarium plants. In fact, Anubias species are an excellent plant to keep with this loach because Anubias can foster significant biofilm/algae growth in an aquarium with moderate to high lighting.
The Spotted Borneo Sucker is a very social species, especially as an adult, so it should be kept in groups. Most small rasboras, tetras, hillstream loaches, gobies, and other small, peaceful fish are good tankmates for this species. Since they inhabit similar waterways, many smaller freshwater goby species are ideal tankmates as well. Due to its small size and diet, the Borneo Sucker can also be kept with dwarf shrimp, although it might eat a few of their fry. Dwarf shrimp are particularly good tankmates in larger aquariums where they can find areas of lower water flow. Peaceful bottom-dwelling fish are also a possibility, but care must be taken to make sure that the Borneo Sucker is not outcompeted for food.
Ordered a couple of things. The Borneo sucker & the multiple plant clippings arrived dead. There was some dealt caused by aus post who advised me that they do not support transportation of live fishes/animals & the onus is on the store sending them.
The store refused to refund money (I didn’t realise that unlike other reputable online stores, they don’t offer live arrival guarantee).
First & last purchase from this store for me.
Great little fish
