I have a rescued (left behind in move) 10 Gallon tank with two male, long finned rosy barbs and some kind of loach, who is shy. Or at least, from my internet research, that's what I THINK I have. When I came to the rescue (Da da da daaaa!) of this aquarium the water was very gross and very low. The Filter (TopFin-20) was on and running although it could not reach the water- who knows for how long. When cleaning it out I discovered it had a half set up under gravel filter. I say half set up because it had the grate thingies but the holes where the filter part goes through were duct taped closed.... I dunno. Obviously a hand-me-down aquarium for little kids. Anyway, I scrubbed the tank and filter which i don't think had ever been cleaned (bleck!) and redocorated it (Not a fan of Spongebob figurines and blue gravel). I threw out the UGF pieces. The fish are a lot happier and way more colorful now and I'm wanting to add more. Sooo, let's hear it........
