Hey guys, so I just picked up my new 180 Gal tank today. It was used for freshwater before, which is what I plan to use it for. I need to clean it before I set it up just because I want to make sure its clean. I've read up alot, and what I've gathered is to use vinegar, but I don't know exactly what kind of vinegar or if it makes any difference. Now onto stock, once I've cleaned and cycled the tank, I plan on adding my current stock plus a few new fish. Heres my list, please let me know what you guys think. Thanks
Current Stock that will be transferred into new tank:
1 female Blood Parrot 5"
2 Clown Loaches 4" each
1 Nicaraguan Cichlid 4-5"
1 Common Pleco 7"
1 Jack Dempsey 6"
White Sand
Driftwood
Rocks
New Fish to be introduced: all will be juvenile or less than 3"
1 Electric Blue Jack Dempsey
2 Gold Severum
2 Clown Loaches
6 Geophagus Altifrons or 3 altifrons and 3 heckellii (can i keep the two different kinds together?)
this isnt my tank, but its EXACTLY the same tank and stand.
