is my tank really OS? I keep getting different feedback on this subject! one says go for it, then another says it's overstocked, then another says go for it! now, my fish sizes are this: betta: 2 inches and NOT growing! glowlights: all around 1 1/4 inch and NOT growing! zebra pleco: 1 1/2 inches and growing! also, I found out my 10 gallon is a 10 gallon long, so there's more oxygen and swimming space.
