I have just bought a green spotted pufferfish who is awesome (his name is Squirt). Squirt has been living in saltwater and has been very happy, right now he has a decoration of a shark, and i wanted to take it out of his tank and use it for my freshwater tank is it okay to switch things from saltwater to freshwater as long as i rinse it off? Also could i use a fish net in the salt and freshwater? (Squirt is my only saltwater fish)

I’m thinking about getting a 75 gallon fish-only saltwater rectangular tank. It’s going to have 50-75 lbs. of live rock, live sand, and a protein skimmer.

My list:
2 ocellaris clowns
1 regal tang
1 yellow tang
1 neon goby
1 hawkfish
Some cleaner shrimp
1 bubble tip anemone OR 1 saddle anemone

Is R.O. water really necessary for this tank?

I need some good suggestions/links for:
Mountain biking
Kayaking
Deep sea fishing
Rock Climbing

I will be staying in the Rockland/Owls Head area.

Me and my friend like to catch bait, like little skipjacks for fun, we fish by quonset on allens harbor but arent having any luck catching any fish there, does anyone know any good spots that they have had luck with this year. Must be in saltwater and in rhode island.
Thanks so much!
