Ich, my poor new aquarium...
New here! New to fish! Here's my story...
20 gallon tank, with filter and heater set around 74. We were evidently wrongly advised to start with neon tetra by a 'fish professional' at a local store. Then we added a 'Mickey' platy. All was good for a week or so. Then after one neon died we added some more to add to the school and they were very happy. Then another 'fish professional' from a different pet store suggested adding 3 danios - which scared the life out of 4 neons - and the rest (10 total) dropped one by one after. I removed the danios about 6 hrs after we put them in and returned them. I forgot to mention that after we introduced the danios we discovered Ich - and we have been treating. Now my last fish, the platy, has died overnight.
So now my tank that is only 3 weeks old - is empty. I wonder if we introduced too many fish too soon? How do I proceed from here? Treat for ich again? How long do I wait before trying to add new fish? Is it too early for a bottom feeder? So many questions... We have tested the water with strips and even taken water samples to a local pet store and they say the water looks great.
Thanks, and hello!
