Hello,
Here's a question regarding environmental research. I bought level one research. Does this also apply to my selling tank or only tank 1 or will I need to purchase it again for tank 2 and the selling tank.

Many thanks,
Marcee

All of your research applies to every tank, so you only have to buy it once!

Thank you so much!

hi,im a new member here. i was wondering why my baby or some adult fishes die when i already bought the aeration system,temperature regulator and the plant of curing from isola.

The more fragile and exotic fishies won't survive unless you research the higher levels of Fish Environment.
