The pink (more red than pink) fish are jewel cichlids. Quite a spontaneous breeder. Will attack anything smaller and nip at anything when they are spawning.

As for the BD, I got only 6. So far so good. Not adult yet. But they are very hungry, turning up my gravel already. So I have to find larger gravel (0.4-0.5cm) to anchor the plants. But they are a beauty. So I may keep all of them until they get unfriendly and fight. Besides, I have started weekly water changes (20%), trimming of plants & vacuming the decaying stuff. Taking out the water chestnut as it takes up too much light & space. Lilies have gone to another tank too. Replacing with more rigid leave plants.
