I'm hoping to save on shipping ($60 per shipment :'( ) and get all my fish/shrimp at once. My tank is 66 gallons. I have 2 30 gallon tanks. I'm thinking the 2 vampire shrimp will go into the main tank right away (it's cycled) and then I'll split the fish into the 2 quarantine tanks. How long should they stay in there? Should I add a few fish from the quarantine tanks at a time to the big tank? If I put large sponge filters into my cycled tank now (rated to 55 gallons each) how long do you think it'll take for them to be populated with bb enough so I can put them in the quarantine tanks? Besides filters and heaters what else do I need in the tanks? I don't have gravel etc but I can put in some things to act as caves and such. Any other tips are welcome! I won't be getting the fish for a little while (however long it takes to get the sponge filters cycled) Thanks!
