So, about a year ago, i had a hifin blue cobalt male and a female red turqoise that would spawn, however, this was in my 180g community, and the pleco's always got the eggs at night. So after adding some SA cichlids, i decided to move the couple to a 40g hex all by themselves to see if I could get them to spawn. It has been a month, and nothing. Water conditions are the same as in my 180, i have even added blackwater extract and raised the temp from 82 to 86, and still nothing.....any ideas or tricks?? PH is 6.6 temp is 86 feeding pellets (hikari bio gold+ ) frozen bloodworms and freeze dried krill.
