Question about danios and the safety of my young fish?
I just got 5 juvenile rainbow shiners for my 20g, and they're currently acclimating and pretty much ready to go into the tank. However, I have a few quick questions. First, the smallest of them is only about 3/4" long, and I currently have two danios in the tank. The danios are going to be moved (as soon as I can catch them...), but I just wanted to make sure it was safe to put my shiners in the tank now--the danios won't try to eat it, will they? I tend to doubt it, since I think it's a bit too big, but I just wanted to be sure. I also have some corys in the tank--they won't try to eat it either, will they? Again, I doubt it, I'm just paranoid.
Second, A few of them are just small enough to fit through the slits on the filter intake. I can't imagine the suction is very strong, but I just wanted to make sure my fish weren't in danger of being sucked in. I don't currently have any sponges or pantyhose handy, either, or I'd use those.
Third, I have the water temp at hair below 74 degrees right now. Does that sound about right?
Rainbow shiners are US native fish and live in cool water. The corys and threadfin rainbows that share the tank don't mind cool temps either, so that's not a problem. :)
