This. The aquarium tab says Blue Planet is a 55 gallon, but that can't be right since an Eheim 2010 measures 8.6x3x3.8 inches. Do you think you could get the measurements of the tank for us? It does look small like you said.
Man I hate being the one to say this, but do you think you can return fish? Even pushing the envelope a little for minimum tank size still leaves you in trouble with a lot of your fish if I'm guessing the tank size right. I could point out some of the problems I see, but I'm worried you might think I'm getting down on you. People make mistakes.
