Switching to Aggressive

[thirdchaos]

After a lot of thought, I decided im changing my 90 gallon reef over to an agressive tank. Which of these fish could i have?
Volitan Lion
Humu Humu Trigger
Porcupine Puffer
Some kind of eel
I'm not really sure what can go together. Im open to any suggestions in regards to stocking. Also, is more or less live rock better? With more, there is better filtation. With less, there is more swimming space.

well if you get a lion the trigger and puffer will shed its fins. A 90gal is to small for a pocupine puffer. And for as eels you would just have to research the one you want. And you are correct lots of rocks = filtration, hardly any rock = more swimming room. Do you have a sump? But some rocks in the sump

I would go with more rock than less rock. When I had my 75 running, I had 90 lbs. of live rock in there. Now that I have my 210 aggressive going though, I have 245 lbs. of rock in there, and I have another 35 lbs. still curing.
A 90 is fine for a volitan, porcupine, and a snowflake or some other type of peaceful eel, but I would not recommend getting a trigger because triggers shred lions. The puffer should be fine (my puffer gets along great with my fuzzy dwarf and volitan), but the trigger could be a problem. Just make sure that you know that you will need to upgrade your tank size to a much larger tank once these fish begin to grow too large.. hence the reason my tank went from a 75 to a 210.
