Matching Fish To Water Parameters
Am I driving myself crazy for nothing? I've been researching fish to eventually stock my 55 gallon tank with. The water parameters depending on the source you look at never seem to match. Some are off my a lot! One says 75-86 degrees for a Pearl Gourami, then in the description for the same fish is says to raise the temperature to 80 degrees when breeding! So I assume that the 86 is probably a typo.
When the fish description shows a range of temperatures, is the optimum temp somewhere in the middle or closer to the warmer end?
What is the most important parameter? Temp? PH? GH? KH?
Then When I decide on a fish to be my centerpiece and look for other fish to go with it with the same parameters, it's difficult to find exact matches.
55 gallon Low tech planted tank. I like Angelfish and Pearl Gourami, And German Rams. I should say, I like the way they look, because I don't have any experience keeping them. Should I avoid German Blues to start with. Live Aquaria says "EXPERT ONLY" in caps!
So what is the best temperature that works with low light, easy plants and say, Angelfish and friends?
