I have a planted 35g / 130L tank which is in the process of cycling. I am most likely going to put in a female betta soon (unless for some reason someone mentions why this shouldn't be done) to perform a fish-in cycle, given that bettas produce barely any waste and since she will be in a planted 35g it should be insignificant and not really effect her (especially given people do this with bettas in 5g tanks). And of course I will also be checking parameters and doing water changes where needed.
Now, as I do plan to have guppies for this tank (4 females), I'm wondering would I be going too far in adding them in as well? I thought about it since they are small and have low bioloads as well, and again its a 35g planted. Will that be too many fish at once? Too much ammonia in a cycling tank? I only want to do this if the bioload is very small and the effect is pretty much insignificant due to such a low concentration given the water's volume.
Also I will be using seachem prime as a water conditioner.
Please let me know if you think this is safe to do, if the ammonia level will still be basically insignificant, or should I just stick to putting the betta, or even none. Thanks!
