Ok when we decided to actually put fish in our fish tank (Believe its a 20gal tank, and we moved about 4 years ago and since then it had the gravel and framed picture of a school of fish, lol) Anways we got A Marble Angel, Placostomus, Catfish (Fairly Small) Coolie Loach, Red-Tailed Shark, Glass Cats...and some others....Well the catfish ended up growing to be about 6 inches long and the ruler of the tank. Not alot of problems until we bought a Marble Fish (Forget what kind) and the second we let it go it swam down to the bottom and sat there. Well the Catfish being bigger and quicker sucked it down (JUST BOUGHT THE FISH TOO!) Then 2 days ago I find my Marble Angel fish floating at the top with no tail and dead....so we took the Catfish back (After refusing to not eat it) and got another Marble Angel...that brings me to my questions (Sorry for the long story
)
Will the be "Rulers" in the Freshwater Aquarium? IE. Such as a big fish scaring off fish. Or you wake up one morning look at your screensaver and your suddenly short one fish....anything like that?
