| a piece of the black plastic like sponge? or the filter cartriges? the 30 has been running since dec 27, i put start right in it that day and had fish in it. it came with 9 cichlids and a pleco and i had no choice but to start it right away, i then took the cichlids to the pet store a week later after finding out they got big and are agressive and got the female sword tail and a pair of orange platty's outta the deal. right now the 30 has a peppered cory, pleco, pair of platty's pair of molly's half black very pregnate guppy a male dolmation molly and 2 fedder gold fish that will go to a pond in spring, i had a black lyretail molly but she had babies with in 3 hours of buying her then she died 3 days later. the fry were born on the 11th, and they are all doing good, i just moved them to the 10 gallon cause i hated keeping them in the little plastic breeder so that they wouldnt get eaten |
