Another Question

Finally got some consistency going on in my tank and now my fish are doing quit well. Two 3" turqouis in a 20 gal. Leaving the water over night with air stone made a big difference as well as daily water changes.

Noticed they are getting a little more aggressive towards each other. No injuries but I am getting worried. Are they like African Cichlids meaning that two in a 20 gal together will end up with one dying??

Advice would be appreciated.

Just a dominance thing, Dan. One fish trying to establish the pecking order. Note that discus are school fish and as such like to have a group, say of 5 or more. The group provides security and spreads out the bully behavior.

Adding 3 more fish also justifies a larger tank! I don't see a downside to this...

Hmmm. A bigger tank is getting tempting :)

Thanks,
