The women will be smaller, with a much more plain pigmentation and also will normally have a narrower body– though they will certainly plump up with eggs.
Once the men as well as ladies have been gotten rid of to different storage tanks, they must be fed a stable diet plan of online and frozen foods for at the very least a week. Now, choose the best fish from each storage tank, and position them in a fully cycled breeding storage tank.
The water in the storage tank ought to be tough water with a pH of a minimum of 7. It should additionally be heavily planted with densely expanding plants, like Water Sprite or Java Moss.
The man and also lady will invest the next couple of days spawning desperately, as well as this occur on and off for a number of days.
