Hello everyone! This is my first time posting on this forum, although I have collected lots of great information by reading previous posts here. This is my first aquarium and I was wondering about when I can get fish and what fish I should get. Right now I have 1 red tail shark and 1 pleco in the tank after an outbreak of ick that killed 3 swordtails and my angelicus catfish . The ick is shedding off of my shark right now and there are only a couple white spots left on his fins. I used coppersafe to fight the ick. I was wondering when I can start adding fish again, and also which fish would be good in my tank. My tank is a standard 20g, with driftwood rocks and shells. My nitrite, ammonia, and ph levels are all very good.
