I found this site yesterday in a panic to figure out what was wrong with my Oscar, I clicked on "contact us" and asked for help. I'm not sure yet which one of you it was but somebody helped a complete stranger and I'm very grateful.
My husband and I have several tanks but our newest and most favorite is our 180 gallon for our Oscars

Since then we've added 2 Green Terrors and 2 Silver Dollars.....the pleco is there but stays hidden.
I know I have a lot to learn and this looks like the place to do it, I'm glad to be here
