Hello all...I have a 55 gallon tank that has been running for about five years now. Most of the fish that I had for these five years have slowly passed away over the course of the six months or so. Basically had some Tiger Barbs, Cories, and Gourami's. I am down to two tiger barbs, a gold gourami, and two cories. I am taking a water sample in to my local Fish Hobby Store (OUTSTANDING STORE) tomorrow just to make sure all is good b4 I buy any fish but wanted to ask your opinions please re adding the following to this tank - all are small in size: 5-6 Albino Corys 3 Angel Fish 1 Bala Shark 1 Bristlenos Pleco 3 Chinese Algae Eaters 3 Nierite Snails 3-4 Gold Panda Mollies 3-4 Harequin Rasboras Thank you!
