  • Cyclopes
  • Daphnia

  • Micropellets
  • Black worm
  • Bloodworms
  • White worms
  • Mosquito larvae
  • Blanched vegetables like zucchini and cabbage
  • Algae wafers

Moreover, make sure to feed them for a couple of minutes, a few times a day, and remove the rest of the remaining food. This way, the fish will not get obese, and the water quality will not be compromised due to food particles as well.

– Water Parameters

Another factor to consider is the water parameters. The fish thrives in soft and acidic water with water microdevario kubotai temperature of 68 F to 80 F and pH level of 6.0 to 7.0. The hardness of the water should be between 18-179 ppm, and a KH of 2-10 dKH is recommended. As you can see, these parameters are fairly flexible.

However, though the fish is hardy, it still needs constant water conditions without too much fluctuation. It will only strive best when it is living in stable water parameters and good quality water. Furthermore, make sure to monitor the numbers on a regular basis, if any fluctuations are noticed, fix it as soon as possible.

Since this fish is small, many people assume that they don’t need water changes and filtration. This is not true, and this fish can’t be kept in a vase or a bowl. The fish needs partial water changes regularly, and there should be proper filtration of the tank with a moderate flow of water.

– Tank Size

The tank size of microdevario kubotai doesn’t need to be that large since these fish are tiny. Although since you have to keep them in a school, the tank size should not be smaller than 10 gallons. The tank size should also increase according to the amount of fish in the tank if they are kept in a community tank.

A 15-gallon tank will be enough for a school of eight fish, and as the number of fish increases, the tank size should also increase. As a general rule of thumb, with each increasing microdevario kubotai, two more gallons of water should be added to the tank. This size will increase even more with different species of fish.

– Tank Decorations

The fish needs a planted tank with lots of hiding places, especially if you want to keep them in a community tank. These decorations will help the fish feel more at home if they replicate their natural habitat.

To start with the substrate, you can have any substrate you want, but a dark-colored substrate will make the color of this fish pop even more. The substrate can be a mix of gravel, sand, rocks, and stones. Next, the tank should be highly planted with lots of driftwood as well. The fish needs plenty of space to hide, as you know.

– Lifespan

The lifespan of this fish is not as much, but it is not that little as well. If you want to get this fish, be ready to keep it for three to seven years in your care. However, they will only reach the seven-year mark if the tank that they inhabit matches their natural habitat and is well kept.

Microdevario kubotai lifespan also depends on many other factors. The store where you buy the fish should be respectable because sometimes you can get a fish that is already sick, so it will not stay alive for very long.

Moreover, the transportation of this fish can take a toll on its health, so it is important to travel on a smooth road as the bumps will make the fish get sick. Needless to say, be very careful where you buy the fish from if you want it to live long and reproduce.

But if the fish still catches any disease, you should immediately quarantine it and begin the treatment.

Tank Mates

You might think that since this fish is peaceful and timid you could probably keep a lot of tank mates with it, but that is not true at all. Although peaceful, it is more reason for this fish to stay among the species of the same kind. It can be kept with some selected peaceful and small fish.

– Ideal Tank Mates

The best tank mates for your rasbora fish are listed below:

Basically, just make sure that the fish is peaceful and smaller in size. Additionally, make sure to have enough space in the tank for these partners to be extra safe and ensure there is no competition for food and territory.

– Tankmates to Avoid

Rasboras are peaceful fish that don’t like to cause trouble and prefer to be in friendly company. So any boisterous type of fish that owns an aggressive nature and likes to pick fights with calmer fish should be avoided as tank mates. Otherwise there will be fights within the aquarium and your timid rasboras might get injured or even die.

Moreover, these fish are fairly small in size. So you absolutely should not keep fish of larger sizes in the same tank as them. Otherwise, the poor rasboras might end up becoming food to the larger partners.

Breeding

Another important part of taking care of any fish in the tank is their permanent home even when it comes to breeding. The tank should have conditions that are similar to its natural habitat to have a smooth breeding process. The natural habitat of microdevario kubotai is a calm and well-oxygenated river or stream that is also filled with vegetation and leaf litter that provides the nutrients and places to hide.

– Pre-Breeding Care

Since you will have these fish in a school, it is very easy to breed them. In fact, you will not even need to do anything special to make them breed in a tank that is well maintained. All you have to do is make sure the fish is healthy, by giving them a proper diet filled with protein.

To attract the female, the male fish will display brilliant colors. When the process is successful, they will finally mate. Since they are egg scatterers, you will find their eggs sprinkled over the tank decorations. After the eggs are scattered, you will find the fry will start swimming within 72 hours or two to three days

– Post Breeding Care

Now, there is a high chance that most of this fry will not survive. This is because other fish in the tank, including the parents, might eat the fry. However, some might still survive if they are born in hidden parts. But if you want to make sure that the fry lives, make sure they spawn in a different tank.

After the breeding process is complete, remove the parents from the tank after two to three days. The fry should be fed and kept in a separate tank until they reach maturity, after which they can be introduced to the previous tank.
