Yo yo loach (Botia almorhae) also pakistani loach, almora loach, botia yoyo is a very beautiful fish that belongs to loach family.
It has silvery body with dark vertical stripes and its reproductive species also have some bluish shimmer. Botia almorhae comes from India and Pakistan.
Besides Pakistani species are a bit less saturated with color than Indian ones. Of course, they may be two different subspecies or even two different kinds, because their classification isn’t very precise for the moment.
The fish name originated with the help of famous photographer Ken Childs who has been working in aquarium husbandry industry for more than 20 years.
When he was taking pictures of fishes for one of his report, he noticed that coloring of some species formed something like YoYo letters compination.
When he named Botia almorhae as YoYo fish in his article, the name was remembered by the readers and it became widely spread among English speaking audience.
Habitat in the wild
Botia almorhae also called botia yoyo or pakistani botia was first described in 1920. The fish inhabits in India and Pakistan.
Its habitats are waters with slow flow or impounded waters, so it can be said that the fish doesn’t like water flows presence.
Backwaters, ponds, lakes are typical habitats for yo yo loach. It feeds mainly on insects and water plants can be eaten, too.
Loach size is about 6.5 cm (2,56 in). However, in the wild the fish can grow much larger – up to 15.5 cm (6.1 in) long.
Yoyo fish average lifespan is about 5-8 years, although it’s been reported about some species that lived over 16 years.
Yoyo loahces juveniles coloring differs from the one of mature species. The juveniles have stripes, but they obtain characteristic net-like or marble-like coloring by the age of 3-4 month.
All Botiidae family species have a spine a bit under their eyes, that is usually hidden is some kind of skin “pocket” and so it is invisible.
But when the fish gets scared or stressed the spine slides out like a knife blade. The spine is very sharp and when transporting the fish this spine can indeed stab the bag, where the fish is. So, to be safe it’s better to use two bags – one inside the other.
Also, you have to be careful when catching the fish, since it often happens, that the fish tries to protect itself with these spines and they get stuck in the lift net. Also just a pin with these spines itself can be rather painful.

Difficulties in keeping
Pakistani loaches are rather enduring fishes provided with appropriate care. The fish isn’t recommended for beginners, since it’s large, active and it requires stable water parameters.
Also the fish has very small scales, that makes it sensitive to illnesses and medical treatment.
Care and feeding are very easy, since it eats all types of feed. As all bottom feeding fishes, yoyo loach fish needs the feed that fill reach a tank bottom.
Also including the fact that this is a night fish, it’s better to feed it shortly before turning off the lights – you can give granules that fall on the bottom or some frozen feed.
The fish enjoys a lot life feed, especially blood worm and tubifex. Also Botiidae fishes are known to eat snails eagerly, so if you want to get rid of snails in your tank – yo yo loahes will help you with this just in a few days.
But remember, that it’s very easy to overfeed Botiidae species, since they are very insatiable and they’ll eat till they eat way too much.

Keeping in a tank
In the wild the fish lives in relatively still water of highland streams. It’s better to keep Botiidae almorhae in a group of about 5 fishes in a tank.
The fish is considered the one that adapts easily to new conditions. It behaves rather peacefully. Yo yo loaches have social pattern of behavior just like clown loaches.
They can fight and at that their body color becomes significantly lighter and the stripes almost disappear. The fishes don’t cause each other any harm while these fights.
To avoid them it’s good to put a lot of covers in a tank – caves, snags, plants will do. Tank bottom substrate has to be fine and rounded just like for all fishes from loach family, since they actively dig it and can injure their barbels.
Yo yo loach tank should have moderate and diffused light.
The fish is a hiding expert and it can get into very narrow cracks. Sometimes the fish can stick there, so don’t be lazy and count the fishes from time to time. Any tank with Botidae fishes should have a lot of covers for the fishes to feel comfortable and safe.
They especially like some narrow places, so you can use some ceramic or plastic tubes for this.
Yoyo loach fish is very sensitive to water parameters and purity, so it’s not recommended to put the fish in a new tank where water parameters aren’t stable yet. Filtration and frequent water renew are necessary. Water chemical composition should be the following: pH 6,0 – 7,5, hardness dH <12
Temperature: 19 – 27°C. Optimal temperature 25. At the condition of high water aeration (because when the temperature rises oxygen content in it decreases) the fish is ok with razing of water temperature up to 30 C.
Compatibility with other fishes
As a rule Botiidae almorhae fishes are good tank mates for other kinds of fishes, but it’s better to avoid aggressive tank mates and raptorial feeders.
If the fish feels safe, the majority of the time it spends in covers and it can even refuse from feeding.
However, yoyo loach could never complain about bad appetite. It can’t be said that the fish is a good tank mate for species of the same kind, since in a school an alpha male fish becomes a chief and sometimes he haunts other yoyo loach males.
One can see between yoyo loach female and male only when they become reproductive. Males have more slim body than females and the latter are a bit larger and more bulky than males.
Surprisingly, the fish that adapts so easy to tank conditions at that breeds very poorly in it.
There is no reliable data as for yoyo loach breeding and yoyo loach fish juveniles grown up in a tank by amateurs aquarists.
It is considered that yoyo loach fish breeding can be performed only by professional fish breeders with the help of hormones injections.
