I'm a brand new member, and am looking forward to some informative discussions.
I'm not a complete novice, having dabbled in aquariums over the last thirty five years, but I still have a lot to learn.
After a 13 year hiatus, I bought a ten gallon a year ago, just to house a couple goldfish and two Corys...yep, the goldfish outgrew the tank!
So, I found a 20H at the local Goodwill, but the goldfish started to outgrow that too. I now have them in a 50 gallon preform pond outside (see my avatar) and my current tank has Zebra Danios and Corys, Hornwort, moss (Java?), assorted bulb plants I've not bothered to identify yet, and three mystery snails (two gold, one black).
Yesterday I found a 29H at a yard sale...
