Hello i am currently training my pet to be a 20 boost tank its pet species is kacheek.
I want to know where I can find a petpage or something like that, that has a list of which weapons are the best for a tank of any boost. I saw one a while back but I cant find it anymore
Please help

What is a tank? I have heard that expression many times but I have no clue what it means. I'm thinking a defensive pet, I'm not sure.
Its a pet with high HP and Defence and low strength. Its built to last long in battle without taking so much damage away.
"Tank" = low Str boost pet designed to take advantage of the flaws in boost-based battling and the NCW league structure. Generally tank pets have at least 2 more defense boosts than Strength boosts and some have 5 or more defense boosts over their strength boosts. Generally they also have an equivalent amount of Hit Points. Thus a "20 boost tank" might have 85 Def and 85 HP, and seek to fight other 20 str boost pets.
It's a horribly inefficient and costly method of training, and it is of very limited use in 1player so I really don't recommend it.
But if you want to go that route:
Everlasting Crystal Apple is almost a must at the lower end.
Then defensive weapons such as:
Tower Shield
Hobans Hat
Sophies Magic Hat
Air Faerie Crown
Mask of Coltzan
Ghostkershield
Faerie Tabard
Clawed Shield
can be used to exploit the defense boost to full advantage. Frequently tankers will attempt to cover all icon types such as with Hobans Hat + Tower Shield or Ghostkershield + Faerie Tabard and win by using just species abilities. Other tankers may just rely on solid dual duty defensive combos such as Mask of Coltzan + Air Faerie Crown.
Since in the NCW leagues getting a massive defense boost advantage usually means that you are fighting against opponents with higher Strength boost than you, many tanks rely on offensive weapons which deal reflected icons such as
Prickly Potion or
Glowing Cauldron. These weapons also work to get through the defenses of rival tanks.
Bracelet of Kings has recently gained in popularity among tanks as it can both multiheal and deal reflected icons, but its randomness does work against it.
The relatively new
Glittery Faerie Dust is pretty strong against tankers, but it does cost enough that any sane opponent is better off just training past the point where tanking is cost-effective than buying one.
