Fork-tailed Loach
Cobitoidea sp.
Fork-tailed Loach (Cobitoidea sp.) — Intermediate care, Peaceful, under Loach. Minimum tank in the app: 46 US gal min; aim for 73–84°F and pH 6–7.8. The Fork-tailed Loach is ideal for aquarists seeking an active, engaging bottom-dweller that thrives in slightly warmer waters.

Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Fork-tailed Loach Tank Setup
To foster a healthy environment, incorporate varied substrate for burrowing and ample hiding places with rocks or driftwood, allowing for both open swimming space and sheltered areas. Ensure moderate water flow to mimic their natural habitat, and consider subdued lighting to reduce stress and encourage natural foraging behaviors.
What Do Fork-tailed Loachs Eat?
Fork-tailed Loaches are opportunistic feeders, often competing for food, so ensure you provide a varied diet including sinking pellets, vegetables, and occasional protein. Their feeding speed is moderate; however, a lack of food variety can lead to health issues or dull coloration.
Fork-tailed Loach Tank Mates
Ideal companions include similarly sized, non-aggressive species that occupy different swimming levels, such as tetras or rasboras. Avoid pairing with overly aggressive species or those that might nip at their fins, as this can lead to heightened stress and aggression. Intraspecies dynamics are generally peaceful, but overcrowding can induce competition.
Are Fork-tailed Loachs Good for Beginners?
We rate this as intermediate. Budget time for testing, maintenance, and watching behaviour if the water looks fine but the fish do not. Aquarists often underestimate the need for hiding spots, leading to stress and aggression among tank mates. Neglecting water parameters can also cause health issues, as they are sensitive to pH fluctuations and temperature extremes.
