when my tank fully cycled, passed the diatom, cyano and some algae stage, I got a BTA.. when I could handle BTAs no problem, I moved on to Haddoni. That's about 10 months into the hobby. I killed quite a few Haddoni from lack of knowledge on QTing..
once I got the cipro down, I was able to keep most Haddonis I purchase.
of course choosing a healthy one is the most important factor. Diversden Haddoni has always been healthy for me. Or LFS Haddoni that hasn't came out of shipping bags yet
Low flow and deep sand bed will prevent it from moving too much. I like to dig a hole next to the rocks and plant the Haddoni there.
