35 gallon freshwater aquarium

I have really nice fish.
-2 lyre tail marble mollies
-2 young lyre tail yellow mollies
-2 red tail black variutus
-1 female marigold variatus
-1 Male Marigold variatus very very nice extremely yellow sail fin
-6 Neon Tets
-2 Glow Light tets
-4 cool Gold tets
-2 red swords
-2 red wag swords
-2 rainbow blue wag platys
-2 Sunset Coral Dwarf Platys
-1 Male guppy 6 baby guppies 3 male 3 female

 

sounds pretty overstocked to me remember 1 inch of fish per gallon

 

It sounds like alot. But many are quite small
ex
-wag swords
-dwarf platys
-tets
-yellow mollies
-guppies
2 mollies and 2 swords are the only ones larger than 2

 

but they get bigger and you should have room for their adult size.
ex
-6 Neon Tets x2 inches = 12
-2 Glow Light tetsx 2 inches= 4
-4 cool Gold tets x2 inches=8
______________________=24inches right there

cramped tanks lead twards aggression

 

My male marble mollie is the only aggressive fish in my tank. But its nothin serious. He did kill one of my other male marbles but it was over a female. Besides that none of my fish are aggressive and I don't have many multiple sets of males

 

I know but even "peaceful" fish can become aggressive when not provided enough space.

 

its not aggresion that's many only with chcilids and other aggresive fish it more the waste they produce but if u keep the water changes up it should be fine

Peace Out Callum!

 

I do do weekly water changes and test the water
