Hi all!!! I look forward to reading posts and keeping in touch with the community of MFKprs!! I use to keep 10-30 gallon community tanks (bettas, tetras, barbs, etc.) Last year I purchased a 55 gal to start growing a Black ghost knife (recently purchased at 3 inches) and a fire eel (kept for 9 months, started at 5 inches now roughly 8 in). I know both these fish will need a larger home, I intend to have them transferred into a 150 by the end of this year.
