To Keep these hill stream loaches and other river fish we need specialized tanks, though this has been discussed before, we can still refer to a great article by Nathan Hill who creates a useful aquatic device for those who want a river biotope tank with a more natural flow. Here's how to do it...
"The secret to setting up a better river aquarium"
If we absorb the new documentaries and scientific papers we can constantly learn more and more about the biotopes our fish come from. However, one tank concept continues to elude fishkeepers — the riverine aquarium....
Of course, The Balitora mysorensis from the Cauvery river are still kept separate. The rule of Never mixing fishes of different habitats, even if they appear to be of the same species is strictly adhered to.

New Description :-
Balitora laticauda, a new species of stone loach
(Teleostei: Cypriniformes: Balitoridae) from Krishna River, northern Western Ghats, India )
Abstract: A new species of stone loach Balitora laticauda is described from the Krishna River, northern Western Ghats, India. It differs from all known species of the genus in a combination of characters including: 10 transverse bands on the dorsal surface, deeper caudal peduncle, two prominent rows of papilla encircling upper lip where the proximate row has small papillae while distal row has larger papillae, 66–68 lateral line scales, 8–9 simple rays in pectoral fin, two simple rays in the pelvic fin and pectoral fin not surpassing pelvic fin base. The new species also differs from its related species in the ratios such as caudal peduncle length to depth (2.21–2.89), standard length to body depth (7.48–8.72), head length to head depth (2.11–2.50), head length to interorbital distance (2.20–2.96), head depth to head length (0.42–0.47), eye diameter to head length (0.13–0.17) and head width to gape of mouth (3.12–4.78 ).As percent of standard length B. laticauda sp. nov. differs from other related species with respect to caudal peduncle depth (6.3–7.4%), caudal peduncle length (15.0–20.0%), body width at anus (8.7–11.5%), body depth at anus (9.1–11.4%), pre-dorsal fin length (43.7–47.4%), prepectoral fin length (12.9–16.2%), pre-anal fin length (74.3–79.3%), pre-pelvic fin length (44.4–48.3%), pelvic fin length (19.3–23.7%), pectoral fin length (24.1–28.9%) and body depth at dorsal (11.5–13.4%).
Balitora laticauda (Bhoite et al. 2012) is so-named due to its relatively deep caudal peduncle when compared with its Indian congeners B. brucei and B. mysorensis, the name being derived from the Latin latus, meaning broad, and caudus, meaning tail.
It differs from other members of the genus by the following characters: possession of 10 transverse bands on the dorsal surface; a relatively deeper caudal peduncle; two prominent rows of papilla encircling the upper lip with the proximate row possesing small papillae and the distal row larger papillae; 66–68 lateral line scales; 8–9 simple pectoral-fin rays; two simple pelvic-fin rays; pectoral fin not extending beyond pelvic-fin base. There are also a number of meristic differences.
The new species is known only from a handful of localities within the Krishna River system in Maharashtra State, and was collected alongside a number of other fishes including Rasbora daniconius, Pethia ticto, Puntius sahyadriensis, Hypselobarbus kolus, Tor khudree, Mastacembelus armatus, Channa gachua, and Lepidocephalichthys thermalis.
Habitat was fairly typical of those preferred by balitorid loaches with clear, well-oxygenated water flowing swuftly over substrates of boulders, rocks, and cobbles.

I have 2 pairs of loaches. Bought from LFS. On is the zebra loach and the other is the yoyo loach. both are 1/2 inch long or under. They prefer to hide mostly and stay near the filter.
They tend to find food in the bottom of th tank but on occasions will rs etc teh top to get it and will chase other fish away too.
Will post pictures.
I am a new aquarist
