This has to be the fastest research to purchase time ever!
Question and inquire one day,
And the next purchase a tank , and fish ,
The tomato clowns are too beautiful to sacrifice and I will guarantee your tank will begin a cycle in a couple of days after adding these 2 fish .
The rock is too clean/ new looking for it to be cycled .
But as for a few other threads I've read ,
The best lesson is self taught .
