Help for my tank

[nnacho528]

I have 2 mollies, a lyretail swordfish, two head and tail light tetras, 6 long finned danios, and a pearl gourami in my 20 gallon tank. What should the temp, pH, and anything else, be? Currently, the temp is 77 F and the ph is a little under 7. Thx for all the help u guys are great!

I think swords generally like bigger tanks, and you'll need a few more tetras, bring the school up to 6-8, for them to be happy. Maybe swap the two you have for more danios?

Don't mess with your pH and other parameters any more than you absolutely have to. As far as temp goes, you should probably be ok there.
