I'm working on a 20 gal long aquarium and I have a powder blue gourami that will be going in this tank when it is ready and cycled. The gourami is the center piece of the tank and the only reason I'm even getting another tank lol I can't put him with my bettas I can't put him with my Barb's and tetra glo fish and he can't seem to stop killing my shrimp like I mentioned in a post and he is bullying the green Cory cat fish for whatever reason he is a mean guy. I'm wondering First off what fish can be safe with this gourami in a 20gal tank? For substrate I usually have spare but this time I don't n I was reading about u can use play or pool filter sand in aquariums? Is that safe? Isnt it cheaper then aquarium sand? Is play sand/pool filter sand a good bed for good bacteria?

A: You might be able to get play sand, but you'd have to be vigilant in looking at the materials. Additives, colors, heavy metals. I honestly would pay the extra buck for the aquarium sand. It has beneficial bacteria with it.

B: If your gourami is outright hurting the other fish, then maybe put in some semi-aggressive fish in with him. May I recommend another Gourami? That may settle his issues.
