Added 10 danios to my tank last weekend, and only ended up losing one (pretty good for petsmart stock at least around here) and they've been settling in nicely. I'm noticing behavior i've never really seen in them though. In my 65 gallon (tall) tank I have two canister filters, one that is just plain Jane regular setup and everything, but on the second one I took the outlet nozzle off so the outlet tube just flows straight down to the substrate. I did this since this tank is an absolute skyscraper and not much water flow gets down to the substrate and plants otherwise, and it seems to be doing a good job lifting detritus so far. I don't know if these danios are just being like this because they are small/young, or if they love playing in the downward flow, but they WON'T GET OUT OF MY PLANTS. Under the downward flow I have a pretty big bush of about 4 crypts and this rock I covered in moss. They just absolutely love gliding over this rock and darting in between the crypts. I absolutely love watching this behavior, but I'm just wondering if this is normal? I've only ever known danios to be mid level swimmers.
