I liek your set-up, but you have way too many fish.
Clown loaches will reach 12-14". Tank size of 75+ gallons. Bala Shark
wil reach 14-18", and should have at least 3 in a group. Tank size of 125+ gallons.
Pleco's will reach 5-24", depending on specie, and they poop as much as a 10-48" fish. What kind do you have? Most will need a 100+ gallon tank with very good filtration.
Giant Danios wil get 6-8". Tank size of 55+ gallons.
The Guppies will reproduce like crazy if have you males and females.
Neon Tetras should have at least 6 in a group.
Platies should have at least 5 in a group.
Silvertip Sharks will reach 24".
For this set-up, you will need a 200+ gallon tank.
What are you water params? You need to get some out.
