You can successfully keep Rasboras as Angelfish together with careful planning and tank preparation.
Angelfish are cichlids that can show aggressive tendencies, especially during breeding times.
Rasboras, on the other hand, are relatively small, peaceful schooling fish. But despite the differences, these species can coexist well in the home aquarium.
The Tank Setup
First, you’ll need an adequately sized tank – aim for at least 40 gallons or more.
Dense vegetation and plenty of hiding places are also key to reducing aggression and conflict.
Plant at least 60% of the tank bottom with hardy plants like Amazon swords, Java fern, and moss.
Arrange decor like rock caves and driftwood to create visual barriers and retreat areas, especially for the rasboras.
Choosing Your Fish
Select young, juvenile angelfish that are small enough not to view adult rasboras as prey or competitors initially. A trio of angels is a good number to start with.
For the rasbora shoal, varieties like harlequin rasboras and galaxy rasboras work very well.
But you can experiment with other peaceable shoaling rasboras too. Shoot for at least 8-10 rasboras to establish a stable school.
Feeding and Maintenance
Provide a nutritious diet, including commercial foods and occasional live treats.
Well-fed angel fish tend to leave tankmates alone.
Perform regular water changes and maintenance to keep water parameters optimal. This also curbs aggressive tendencies.
Observe Behavior
Even in ideal conditions, conflict can crop up. Monitor your angelfish and rasboras, especially during feeding times.
If any fish seem stressed or are getting bullied, promptly remove aggressors.
Be prepared to adjust stocking or tank layout if needed to maintain harmony.
