Compatibility Question
 

Hello,
I used to have two separate fish tanks that looked like this:

1) small tank: two guppys (red and yellow)
2) large tank: powder blue dwarf gourami, red platy, 2 neon tetras (lost one to sickness) and 3 rasboras.

I just added the two guppys into the larger tank to save desk space.

Should there be a problem with the guppys in the larger tank with those other fish?
Right now they are swimming at the top, but I only added them less than 5 minutes ago.

Thank you and I know that I should have more neon & rasbora, I am in the process of doing so.

Update: The guppys are still at the top of the tank, but the platy seems to be "following" them by swimming right to the side of them. Is that behavior normal?

I don't see any real issue. The platy is probably curious; I frequently observe fish swimming close to or along with new fish of another species.

wouldn't the dourami attack the guppies

I had thought about that actually. Betta will, it is the bright colouraton. And larger gourami would. A dwarf gourami might be OK. But I will readily defer to anyone with contrary experience.

I was in a fish store last week, and stopped in front of a tank containing 5 or 6 Blue Gourami [actually, there were 2 "blue" and 2 "gold" and 2 "opaline" but they are all the same species]. Three neon tetra were also in the tank, and I thought, that's not a safe combination. I had scarcely "thought" that before two of the gourami closed in on the neons and within about 10 seconds one neon was completely digested by two gourami; a tiny fragment of skeleton drifted to the substrate. One of the gourami then turned and eyed and then lunged at another neon. I called the clerk over and she said the neons had jumped over from the adjoining tank, which I had assumed was the case. This points out why I keep saying, no large gourami with small fish.

yepp, very true
