I got new fish: cloan loach, serpae tetra, bala shark

I would really try and get that platy out of the 6 gallon. They need room as they roam around quite a bit. I am wondering if you moved the tank decorations around some and then turned off the lights and THEN put the platy in with the others, maybe it would work? :confused: Just a thought.
 
platy is now in the 20 :)

how about:
3 blue tetras (in the 6 for now...to the 20 when they get bigger?)
1 ruby barb in the 20
 
I would ad a vote for white clouds in the 6 gal. I love my white clouds and they do great with my betta in the 5gal

I was just sitting here thinking beatta, to me a 6 gal. is perfect for a beatta some plants and maybe a trio of one of the really small types of cories. beatta's are really cool fish when you give them room to swim. I know nothing of white clouds, but they seem pretty popular.
