absolutangel04 said:How big is your tank? I agree with the identifications made. All these fish are hardy, tropical fish. There are not really any tricks to keeping them besides keeping their water clean, getting a good quality food, and makind sure they have enough space. Honestly, that doesn't seem like a very big tank for all those guys.
You can take a tape measure to measure the tank, then google the conversion rate to see how big it is. I agree that it is very serene. Welcome to the hobby!
