Palace119 Power Tools

I use a 20-40 power filter w. carbon.

I have a bubble curtain.

4 live plants. (Melon sword, chain sword, lily red and green)

Okay now for the fish.

I use stress coat organic and tap water treated with AquaSafe.
I also add aquarium salt to help fish keep electrolytes.

I also have a vacuum siphon and do this once every 1-2 weeks and change 25% of water.

I monitor levels with a test kit.

I feed my fish 2x a day with tropical flakes and give them treats of bloodworms every now and then.

Now I have a school of (6) GloFish

4 bettas- 3 female and 1 male. They get along great!!!

4 fruit tetra's. Mixed color.

1 small SAE.

2 snails trapdoor.

Question...is this okay?

And these snails suck should I replace them with Ramshorn snails?

Tips and advice would be greatly appreciated.
Also there is a house for this fish to hide in
