Just set up my 55g last night for brackish. It was a growing out home for my parrot cichlids until I moved the to their new 120g home. Am rescuing a red scat from a client who has it in fresh water...so this will be his new home until I find another used large tank to upgrade him to. Going to try some figure 8 puffers with him, have them on order from the LFS so hopefully have them in the next few weeks.
