First you need 7 accounts. Note not all have to be normal accounts the only one that has to be a full account is the structure trader because you need to be high level to make the fish tank. Take however many accounts you have and then create however many trial accounts you need to have 7 total. Side note, in case some don't know, tial accounts can complete collections. Get 6 poles and bait for however many you are going to have afk fish at a time. I used 6, I put 2 on naboo 2 on endor, because they have the most amount of rare fish endor buzzfish and endor trout, naboo fatfish etc. then 1 on yavin and 1 on dathomir. Once they start getting full have your last account toon run around and pick up the fish, maps and fishtank parts. Then about every 2 to 3 hours check on them filet the normal fish and destroy them. The reason for this is so you don't have to keep stopping to go get bait. When you filet them you get chum which you can use for bait. As you get the rare fish add them to the collection of that toon till you have all the ones you can from that planet you are on. Then just deposit them all in a house and pick up the ones you dont have add them and you get the schematic for completing the collection. Once you have 13 schematics and enough fish tank parts to make 25 tanks pick them up with your trader and get the fishtank parts and start crafting i did this just last week and got server first for it. It took about 6 days to get all the fishtank parts u should have all the schematics in about 3 maybe 4 days. Use the macros from this post.
