Just some relaxing video of Rasbora fish (Phoenix rasbora) schooling together in a group of 8.
Some rare footage of my Boraras Merah (close relative of Chili Rasbora) schooling in a tight formation. They don’t do this very often. Most of the time they school loosely, or even do their separate stuff. In the middle of my filming, Charlie the poodle is curious and watches as well!
Some Trivia: 7 of the Rasbora were bought in the same store, but 1 of them was from another batch. It took a few months for the 1 sole rasbora to familiarize and join the 7 other rasbora as a team. Quite interesting!
How to feed Chili Rasbora / Phoenix Rasbora in Community Tank
Chili Rasbora / Phoenix Rasbora and other small Rasboras like dwarf Rasboras have the following characteristics:
Very small mouths
They are micropredators (require “animal” / high protein food)
How I feed them is actually to take Betta food (Hikari Betta Biogold), and crush them with a mortar and pestle. Betta is also a predator hence their dietary requirements are kind of the same (high protein rather than high vegetable content). Then, together with the Neon Tetra pellets, pour it into the tank. There is bound to be food stuck to the container, which we use tank water to soak it and pour it out.
Repeat until all food is dispensed. Due to the numerous powder food in the water, the Neon Tetras are unable to snatch all the food, and the small Rasboras (Boraras Merah) are able to sneak in a few bites. At the end, all Rasboras are well fed as shown by their round bellies.
If the food is not crushed to powder, the Rasboras would not be able to swallow the food easily, and the end result is that most of the food is eaten by the Tetras. It took me quite a few months to figure the above procedure out (I was and still am quite new to fish keeping).
Very low tech 5 gallon tank for my Phoenix Rasboras (Boraras Merah) and Neon Tetras. I just let the plants grow naturally without CO2, with occasional trimmings. If you look carefully, you can see the Horned Nerite Snail eggs (they look like sesame seeds)!
