So…the eggs disappeared from the leaf after a couple of days and the little cichlids are cruising around the tank again. The smaller always follows the larger and they smile, smile, smile.
The introduction of the 11 new fish has been a positive influence on all the fishies, especially the clown loaches who now swim amongst the rainbows and come to the surface at feeding time, barbels twitching!
I have done two partial water changes this week already, one before I put the newbies in on Sunday and again on Thursday but I will test and do another change tomorrow as there will be a period of adjustment while the good bacteria catches up with the increased bioload. Thanks for advice received!
