General Information: Hillstream Loach are members of the family Balitoridae. They are small bottom-dwelling freshwater fish from Asia and there are about 500 species in 37 genera. Although they come from tropical waters they need high o2 so are best kept in cooler tanks. Balitorids are really interesting fish to watch. Although peaceful, most will defend territories, either to sequester feeding resources like a nice patch of algae, or to keep other fish away from a potential breeding site.
Tank Requirements: See Minimum Tank Volume and Minimum Tank Size above
Diet Requirements: Will eat prepared food, but also need a good algae growth for the little goodies (aufwuchs) that grow on it.
Compatibility: White Cloud Mountain Minnows.
Recommendations: A high oxygen tank is required to keep Hillstream Loach at their best. A river tank set up which has had time to mature is advisable.
Common Problems:
Similar Species: Gastromyzon punctulatus, Pseudogastromyzon cheni.
Sexing: Males are usually larger than females and often display stronger colouration.
Breeding: Balitorids spawn in a depression in the substrate alongside a pebble or rock. The male wiggles about a bit to excavate a little hollow in the gravel. They have been known to breed in a Goldfish tank.

 Help Baby Hillstream Loaches

Hi All,

I just discovered that my adult hillstream loaches had mated in my 120 gallon tank. But never knew there were actually babies in my filteration systems until i was cleaning out one of the canisters and discovered one baby so it made look in the my other one and there were more inside it too. had to fire up my 10 gallon and put them in there cause my other fish in my 120 gallon would eat them. but i am at a lost cause I have no idea on what to feed baby hillstream loaches.

Goodness I have heard of them breeding in a goldfish tank before but you are the first on here so well done as for feeding them, which do you have do you know, some need the little goodies that grow on algae but others eat flakes too, any idea how old they may be not sure what to advise food wise but possibly the same food you would feed most fry like brineshrimp, liquifry and first bites by Hikari are good, take a look at loaches online as they have more information on hillstream and possibly a feeding Guide for fry, Good luck and please let us know how you get on

My Hillstream Loach (Cheni) produced 5 babies 5 weeks ago, 3 have survived and are doing very well.

I got some gr8 advice off here, but also off loaches online. A very knowledgeable chap advised me they would be fine left in with parents, and would graze off algae in tank then move onto the wafers that go in for mum and dad. This has worked well, plus they now adore half a grape (thanks for that Violet!).

Hope this helps anyone looking.

An update on my hsl family !

I lost another baby in september 2011, but remaining 2 are fine and appear to be thriving.
They are in the 90 litre tank now with mum and dad, plus some wcmm - all getting on nicely together.

The babies have grown so much, but are still small at the side of mum and dad.

They are lovely fish
