I want to stock eventually a hand full of Paracheirodon Axelrodi (Cardinal Tetra), and two Mikrogeophagus ramirezi (Blue Ram). To get the tank and beneficial bacteria started I put in 5 Puntius Titteya (Cherry Barb). I'm not sure if I just got a bad assortment or bad stock or what but after about 4 or 5 days all but one died. I soon got four more and after about a week I was left with two (one being from the first group). I then got yet a third batch and after a little longer then a week I yet again had two (one from the first batch and one from the third). Again this tank is planted, I've never seen a hint of ammonia, nitrite or nitrate. All 0. ph is about 6.6. ( Tests done using a brand new api master drop test kit I bought after the second batch because I thought my current one expired and wasn't showing me the correct readings) Temp is about 79 degf.
I don't want to just leave the remaining two in there all alone and under stress but I really don't want to keep going through them like they're going out of style! I'm scared to get some Cardinal Tetra because they're about twice the price and i don't want to blow through them either.
I didn't take any pictures of the deceased, but from what I could tell they looked "normal" I guess you could say. I'm just not sure what i'm doing wrong.
Thanks for any ideas.
Are you buying the Cherry Barbs from one location? Is the pH of your tank close to same as tapwater? No chemicals other than Dechlorinator? CO2?
You mentioned a couple months ago a ten gallon tank with Barbs and cory's. I would borrow some of the filter material from the cycled?ten gallon and place this material in the filter of the 20 gallon.
If this isn't possible,then try and let the tank run with the remaining barbs for a few weeks as bearwithfish mentioned, then slowly add another couple fish (different source) and wait some more.
At lower pH, the bacteria needed develops more slowly.
If you managed to cycle the ten gallon, then I am confident that the 20 gallon will cycle as well.
Could very well be a bad source of fish that you are getting.
