Reticulated hillstream loaches are some of the most unique and fascinating critters you can introduce to your home aquarium. With their distinctive patterns and algae-eating habits, it’s no wonder they’re becoming more and more popular in the aquarium hobby.
But keeping these fish happy and healthy requires some specific knowledge. They need a tank set up that mimics their natural environment to really thrive. This guide will provide you with everything you need to know about reticulated hillstream loaches care, from tank setup to feeding and everything in between.
All about reticulated hillstream loaches
Species and origin
The reticulated hillstream loach is scientifically known as Sewellia lineolata, but they’re also known as tiger hillstream loaches or gold ring butterfly suckers.
These loaches are native to Southeast Asia, and you can often find them in the Xi Jiang River System in Southern China.
Appearance and size
These cool-looking algae eaters typically reach 2 to 2.5 inches (6.4 cm) in length, and if they’re well cared for, they can live up to 10 years.
Setting up the ideal aquarium
Reticulated hillstream loaches need a specific environment to thrive. Here’s what to keep in mind when setting up their tank:
Tank size and setup
A 20-gallon tank is the smallest you should consider for these fish. Because they come from fast-moving streams and rivers, you’ll want to create a river biotope environment for them.
Cover the bottom of the tank with sandy or fine gravel substrate and add smooth rocks and caves where they can hide. One thing to note: these fish are known to jump, so be sure you have a tight-fitting lid on your tank.
Water parameters and filtration
Reticulated hillstream loaches do best in water with a pH between 6.5 and 7.8 and a temperature between 68 and 74°F (20-24°C) – some sources say they can tolerate temperatures up to 80°F (27°C).
They also need moderate to strong water flow, so use powerheads or small filter outlets to create a current in the tank. A quality filter system is a must, and be sure the tank is fully cycled before you add any loaches.
Diet and Feeding Habits
Reticulated hillstream loaches are primarily algae eaters in the wild. That said, you’ll want to supplement their diet in your home aquarium.
I feed mine a variety of foods. They seem to enjoy:
- Repashy gel food
- Sinking algae wafers
- Live and frozen foods like bloodworms and tubifex
- High-quality dry foods
Feed your loaches once a day. Be careful not to give them too much food at once. As with any fish, overfeeding can lead to water quality problems.
Which fish make good tank mates?
Reticulated hillstream loaches tend to be peaceful and get along well with others. You usually won’t have any problems if you keep them with non-aggressive fish that are about the same size.
You should avoid keeping hillstream loaches with boisterous or aggressive fish, or large predators. These fish will likely stress or harm your loaches.
Some good tank mates include:
- Dwarf shrimp
- Other peaceful fish of similar size
As with any aquarium, do your research before adding new fish. This will help to ensure a harmonious and healthy environment for all your aquatic pets.
Breeding Reticulated Hillstream Loaches
Breeding these loaches can be tricky, but it’s definitely possible with the right setup. Here’s what you need to know:
- Ideal Conditions: To encourage breeding, you’ll need a well-established aquarium with plenty of food and hiding spots. Think mature ecosystem!
- Spawning: These loaches usually spawn in groups, laying their eggs on flat rocks. A good strategy is to remove the adult loaches after spawning to prevent them from eating the eggs.
- Raising the Fry: Once the eggs hatch, the tiny fry will need special care. Microworms or baby brine shrimp are excellent first foods. To keep the fry safe, cover your filter intake with a pre-filter sponge. The fry will also graze on mulm, infusoria, and algae, so a well-established tank is key.
- Sexing: Telling males and females apart can be tough, especially when they’re young. Generally, males are larger and more colorful than females. Buying a larger group increases your chances of having both sexes. Sexing juveniles is difficult, so patience is key.
Keeping your loaches healthy
Reticulated hillstream loaches are sensitive to water conditions, so keeping their tank clean is critical.
Here are some tips:
- Change the water regularly. Plan to change the water once a week, using water that is the same temperature as the tank water.
- Monitor water quality. Test the water frequently to make sure the pH is stable, between 7.0 and 7.8.
- Perform regular maintenance. Keep the substrate clean and remove any algae buildup.
Putting It All Together
Reticulated hillstream loaches need a well-maintained tank with the right water flow and temperature. They also need a varied diet. If you can meet their needs, you’ll be rewarded with the antics of these unique and appealing little algae eaters, and your tank will be all the better for their presence.
