Have had my 10 gal up and running for over a year in the current configuration and just wanted to ask your opinion about whether it is full already or if I could reasonbly put in another dwarf fish. It's a full 10 gals and I have a tetra powerfilter in it. Right now I have one male betta,two zebra danios, and one dwarf gold spot pleco. Could I put in another dwarf pleco or maybe something else? If I could, any ideas would be helpful. I'm going to research for a week or two of course before doing anything, but thanks for the help.
