Hello - I have been reading the forums for a while and finally decided to join. We have recently set up our 60g aquarium again. It has been sitting running fishless after the last murderous cichlid went to fish heaven. We have a 30g to set up and hoping to catch a biocube cheap at petsmart. We have kept everything from community fish to the most aggressive cichlids. This is a never ending learning hobby with lots of rewards.
