Long story as short as possible: My husband and son went to the pet store and came home with a 1+ gallon bowl, gravel, a few decorations and a FISH, all at once. This was a few weeks ago.
Fast forward through many rescue efforts, Blue Star (named by my 7-yr-old) is as healthy as can be in a small space that I can't heat over 75 degrees. He's a champ.
Now I have a 6-gallon tank nearly set up and I'm doing a fishless cycle, but I'm still concerned about making the transition when the time comes.
I have bacteria starter, but I'd also like to introduce bacteria from the current bowl into the new tank, but that's not really an option because I removed the "plants" (plastic and possibly tearing Blue Star's fins) and all that's left is the gravel and his little house--I don't want to take any of that away from him!
So finally my main question:
What if I do partial water changes in the bowl for a few days (once the new tank is fully cycled) but instead of using "new" water, I swap water from his current bowl to the new tank and vice versa?
Is there any risk using tank water in a bowl with no filter like that? I'm just thinking it would help him get acclimated to the water he'll be in when he moves.
Any and all advice is much appreciated!
