k since u were given about half of the info u asked for and one unnecessary response after it, I will provide u with the rest of the info u asked for.
Grand is mostly on alto but can also be found on tenor and in the pg. (Look on alto) This fish really isn't too hard, it may be for some. If it is for u, then I dunno what to say...just keep looking, should get around 10,000 to 50,000.
Baby Grand is found on Tenor, (not sure if found anywhere else, but look on Tenor.) This fish isn't too hard, just pick a day and spend ur time u have to play TT looking for it, you should get it. (Hopefully.)
Devil and All Star aren't too hard, atleast I think so. Just look for any other fish, they should come after you've looked hard for a day. These fish can be tough though, if they are ur last, then fish mainly in ddl if devil is ur last, mainly in mml or estate if all star is ur last, and always fish at estate on wednesdays if one is or, both are, ur last.
Grizzly is either really easy or a monster. If it is on the tough side for u, don't give up...u should get it between 20,000 and 50,000 fish. Look on Walrus btw.
Again, Full, like Grizzly, is easy or hard. In a lot of cases it was easy, in a lot of other cases, it wasn't. Look in ddl playground or Lullaby Lane, can't be found anywhere other than the ddl territory. You should get this fish after like 25,000 to 55,000 fish. If he is ur last, then ur probably going to be in for challenge, but you will get him.
I'm assuming u have the gold rod so I don't need to post the rod required for each fish. If you don't have the gold rod then reply and I will write it in.
These fish are pretty hard, this is basically all the information u need, but I doubt you will max in a week, probably 2 weeks to a month. On the other hand, if ur extremely lucky, you will max in a week, but that barely happens considering the amount of fish u need.
I believe that u should fish in the district TT puts u in when u log in. It has certainly helped me when I fished. Also, check the fishing hole forum daily to see if someone caught the fish u need or an ultra rare. Go to the district they say they caught the fish in and fish there. For extra self-encouragement, you could open ur book to the fish u r looking for. Don't know if it helps, but I did it...up to u. This as all helped me somewhat and I got my last 2 fish in 2 weeks, which isn't bad.
I guess this is the end of the information I have to give.
I wish u good luck to u on ur fishing journey, it's a tough road but u reach the end eventually.
