Notes
- Electric yellows sometimes display a brown/black 'mask' on their face, however the vertical black barrings that often appears are not natural.
- Some yellows also show a faded yellow colour, having half white and half yellow colouration. These maybe the points to consider while buying.
- Electric yellows are usually mellow and undemanding to keep.
- The fry tends to gain the yellow colour faster if fed on a diet of occassional brine shrimp. The brilliant colours are expressed if fed high quality food and spirulina products.
- IMO electric yellows are best suited in a tank with dark substrate or decorations as the contrasting colours make them stand out.
