I set up a 20G long tank about 3 weeks ago, I am looking to know some general info on breeding GBRs! Eg water conditions, ornaments, How do sex GBRs? Can I keep other types of fish in my tank with the GBRs or will they only breed on there own and so on! My LPS
have lots of GBRs in stock atm, ive heard they pair up from the very start so am I gona be able to see pairs in the store or is there anything I need to look out for?
