Saw a couple of super red sevs at the store today for 10 dollars. Are these hybrids or are they found in the wild if anyone has any info on them that would be great. I also heard they are hard to breed as males are often sterile making me think they are hybrids. I think im just going to get two green sevs for my tank but would like to see all my possibilities. Are they more sensitive to water conditions then gold and green sevs.
