Mary,
I live in Montgomery and the only thing I'd buy from Land and Sea is dog food.
They keep tangs and angels in those cubes meant for crabs and clowns. Half the time the fish are covered with ich as well.
The Petland in Naperville occasionally has nice stock, but again, you gotta watch for ich. I was there Monday and half the tanks had a disease in the tank.
DO NOT buy anything from the ***** in Oswego. That store should not allowed to sell anything saltwater as they kill most every fish that comes through.
The closest store that I can reccomend is Reef Plus in N Aurora. Right on Randal and Oak St. in the shopping center with Tommy's sports bar. Ive been going there for about a year and the guy that runs it is decent. Lots of corals if thats what youre looking for.
Sea Escapes is the store in S Elgin on Randal. Nice little store. Pricey. But beware, they will sell you ANYTHING and say it's okay. (most stores will do the same but this one notorious for selling sharks to a 55 gallon etc.)
There's actually a little store right in Yorkville in a small shopping center right off 34 past Rte. 47 going west, on the left hand side. Not sure what it's called, but they sell a very limited amount of saltwater fish. I wasn't impressed when I was in there last spring, but maybe they've gotten better.
Other than that, the store mentioned in a previos post in Tinley Park is nice. Small, and expensive but decent. Not sure if it's worth the drive if you're not in the area.
Scotts Pet Shop in Westchester is another one that's a little bit of a drive, but they have quite a bit of stuff.
Bottom line, no fish stores are great. If everyone stocked their tank and nothing dies, they would never sell new fish, medications, filters etc. You just gotta do the research yourself, and be patient. It is different from freshwater but MUCH more rewarding, so hopefully you'll continue to work at it and not give up. But it is expensive, and there will be nights when you feel ike you'll never get it right.
If money is an issue, just add things slowly. You'll have more success doing this thing slowly anyways.
Read up on cycling your tank, and research what you eventually want in the tank. Impulsive buying in saltwater will generally lead to trouble. Have a plan and work torwards completing it.
Hope this helps. And good luck.
