Yoyo Loach – Botia almorhae

Fun Fact - The Yoyo Loach gets it's name from the distinctive pattern on the side of its body. If you look at the black stripes against it' s white background, you'll see the letters, Y-O-Y-O.

The Yoyo Loach, also known as a Pakistani Loach, or Botia almorhae, is a freshwater fish that I consider the dogs of the fish family. The reason I look at them as dogs, is that sometimes they'll just lie around. They'll prop themselves up on plant leaves to rest, or lounge right on the bottom of the tank. I've been tricked a few times into thinking they were dead; they'll lie so still. You can often catch them on their sides, or facing straightforward. That's what dogs do. They lie around. Other times though, dogs are very active, and run around in packs, or play with each other. Yoyo loaches do the same thing. This is when they're really fun to watch.

Yoyo loaches will chase each other around the tank, and prefer to live in groups. A yo-yo Loach will grow to around 3-5 inches (7 - 13 cm) long, so the minimum tank size you want is about 20 gallons. I've got a 40 gallon aquarium, and currently have three yoyo loaches, and two Angelicus Loaches (Botia kubotai).

Don't be mistaken that these are just bottom dwelling fish. They may like to hide, but if you get the right ones, they'll be swimming all over your tank. Loaches prefer many hiding places, lounging on rocks, and exploring driftwood. They also love to dig and look for food.

I feed my Yoyo loaches fish flakes. They also enjoy algae wafers, sinking fish food pellets, and snails.

It's not really easy to determine the sex of this fish. Males will have some redness around their mouths, and females will be a little fatter all around their bodies.

This is an excellent community fish. I love the Yoyo loach, and recommend this fish to anyone keeping a freshwater fish tank.

Rainbow Shark

Scavenging for food in the gravel, Soumyakundu's Rainbow Shark is a beautiful example of the Epalzeorhynchos frenatum species. A member of the Cyprinidae family, this fish is commonly stocked in the freshwater community fish tank.


The rainbow sharks blackish-green body is accented by colorful reddish-orange fins. Also known as the Red-finned Shark, or Ruby Shark, this fish is primarily a bottom, and mid-level dweller. They're happy eating most anything. Spinach, lettuce, tubifex worms, algae, and leftover fish food, make them happy.

The Rainbow Shark is a semi-aggressive fish, which can also be very territorial. It's suggested you have just one in the tank, and fish in similar size. Also, it's best to avoid combining the Rainbow Shark with other freshwater sharks, such as the Red-Tailed Shark and Black Shark. Here are a few more characteristics to consider:

  • Grows to 6 inches
  • Tank parameters: 73-80 F; pH 6.5-7.5; KH 10-15
  • Minimum tank size is 30 gallons; 50 gallons preferred
  • Requires moderate care
  • The rainbow shark is an Omnivore

Rainbow sharks are compatible with most barbs, danios, loaches, plecostomus, and the gourami. You just have to make sure and leave them space to establish a territory.

Breeding the rainbow shark in an aquarium setting isn't done due to the sharks aggressive behavior. If you've got the room in your fish tank, and proper companions, the rainbow shark can be a fun fish to keep.
