+1 to PP.
Spottedpee I don't want to sound harsh here but are you taking in or listening to any advice you are being given here by long time experienced puffer/fish owners?
You came to the forum back at the end of November with 3 F8 and 3 GSP in a 30 gallon. You were informed at that time that you would need to separate them and that you would need an 80 gallon min. just for the GSP's. Your reply to that was
WTF I don't have that kind of money
. People here then suggest that you rehome or return most of the fish ASAP, except for 1 GSP or 2 f8 which would be good for the 30 gallon tank you had.
A month goes by with no mention of rehoming any of those puffers but instead at the end of Dec. you buy another larger GSP. At this time you do mention that you will try and rehome some of the others. As of January 11th from the videos you posted you still had 4 gsp (?) puffers in the 30 gallon, and 4 f8 in another I don't know what size tank? You now say you have found homes for 2/4 of your gsp still trying to find homes for 2 more but you went and added a Fahaka. You have already stated that you don't have the kind of money to upgrade to 80 gallons never mind the possible extra work of floor support (if needed) for a 120 gallon. I don't know if you live in an apartment, parent’s home, or have your own home but most apartments and parent’s homes don't allow for that size tank ( I have seen your "studio" from youtube).
Friendly piece of advice as PP mentioned. Return fahaka, rehome rest of puffers and keep one of the GSP for your 30 gallon tank. Down the road you will be more knowledgeable and prepared for the big guy to give it the home it deservers.
