Questionhope you can help i know it will be big just give it to me straight how big do you think a tank would have to be to hold an panther grouper,snowflake eel,porcupine puffer,and a black volitans lionfish would be
Answer
Hello,
Considering that I have a very similar set-up.
I have a snowflake eel, 2 dwarf lionfish, and puffer. I have a 110 gallon tank. I have had no problems with this set-up.
The Panther Grouper get really big and very agressive. I have seen them reach 24 inches. So it will need it's space I would say about 175 gallons. There will be a lot of waste produced by your quartet so bigger is better. You could opt for the 110 and get a dwarf lion/Fu-man-choo instead of the volitans.
good luck
Todd
