I don’t plan on starting this for a couple years I just want to know how big of a tank I would need
I dont have the fish yet… I wont for sometime now so i dont know how big they are Im asking though how big a tank I would need to house them when they are at their adult size

You don’t say the size of these fish, they are salt water, so go for at least 75 gallons so they can grow.
minimum tank sizes are as follows trigger fish 70 gal puffer 90 gal lion fish 50 gal eel 50 gal to keep all happy i recommend at least 150gal tank check out liveaquria.com i use it for most of my Information
Here is a link to a calculator;
It will tell you how many fish inches you can put in your tank (for slender of full bodied fish) I do not know the maximum size for the fish you mention but it needs to be equal or less than the calculation.
Humu Picasso Triggerfish-75 gal
Porcupine Puffer-100 gallon
Volitan Lionfish-55 gallon for the common
Snowflake Eel-75 gallon minimum
Total- 150 – 200 gallon tank
Good luck with that group!
