I am new to the hobby (about 6 months). Over time lose my 2 clowns (at different times). Not sure why. Parameters we fine. Ammonia and nitrite 0. Only left with royal gramma. It’s been 3 months and have not introduced any fish yet. I have a 32 g Biocube. It was cycled early in the year. Royal gramma thriving well. It’s probably been 3-4 months and seems fine. I didn’t notice any signs of disease and as mentioned the royal gramma thriving.
I wanted to start an observational qt with a 10 gallon tank I have. Want to keep it simple as I am new. Just don’t want to introduce anything into my DT. I did watch a BRSTV beginner video (Matthew) describing a noncylcled qt for which water changes should be performed when ammonia levels rise. My question is if the qt will not be medicated anything wrong with putting some rock or sponge and bacteria and cycling to help keep the ammonia in check and avoiding potentially harming the fish?
