I take care of my 55 gallon fish tank at my work place. It is currently home to a Jardini (mellowest arowana EVER), a Pleco, some cory's and a Golden snail. A few days ago my boss threw in some fish that i have NOOOOOO clue what they are. They range from the smallest being under an inch to the largest being abotu 4-5 inches. The mostly hang out at the bottom, but then again i would too if I had a huge arowana hanging around mid tank! LOL! Another interesting trait is they have a reddish orange tinge to the tips of their tail and anal fins. I have attached a couple of pictures in hopes that someone can educate me on what they are!
