Hello everyone! I just got a baby green spotted puffer and have some questions. One is that right now he is in a cycled 10 gallon tank (too small i kno) so i want to move him to a larger tank. I would like a 20 gallon tall and he will have no other tank mates. My question is that i want to get the 20 gallon and jumpstart the tank using the filter from established tank (biowheel 100 i believe) and put it in the new tank as well as use gravel from the 10 gallon and use it in the new tank as well. Basically move all from the 10 into the new tank to jump start it. The question is how long till i can move the fish from the old to the new? Will i be able to add him instantly? And how long till i can add in the brackish water and at what rate? Please help! And will he chew on gravel to file his beak? I have snails to feed him as well as bloodworms. I want to know if the gravel i have will b ok from the old tank or if i should get crushed coral. Thank you! Sorry for the question storm
