Hello all,

I caught a nice, 2" Logperch yesterday. Today he's fine, and even ate a little bit of bloodworm, but he spends most of his time swimming up the side of the tank. He does occasionally stop and hop around the rocks and stuff, but usually he just does laps up the side of the tank. Why is this? is this because of lack of sufficient current? Also my Blacknose dace seem to do this a lot.

Thanks in Advance.

I've seen newly introduced darters do this swimming behavior. My interpretation is that they're trying to spread out. Logperch in particular usually work a large territory looking for food, so all but the largest aquarium is a tiny area for them.

Logperch do use water column habitats, and they do have a swim bladder. So this behavior is not unusual.

I've noticed my logperches swimming around quite a bit.

I just got my first logperch of the year a few days ago along with a bunch of other sweet darters. My logperch and my two blacksides swim at the glass constantly. I'm not worried about it cuz i've olny had them for 2 days and I've had them in the past and after the first week, they will calm down and settle in to aquarium life. :biggrin:

This may be a little esoteric, but attached is a pdf of my all time favorite darter ecology paper. Greenberg clearly shows that all the Percina species at the study site (Little River), spend a lot of time off the bottom. Interestingly, the snubnoses spend more time off the bottom than other Etheostoma.

Thanks a bunch guys!

The Logperch has calmed down and no longer swims against the glass. He's started eating well on a diet of frozen bloodworm.

Hadn't seen that before, great paper, I can see why it's your all-time fav.

I really love Eth. rufilineatum (redline darter) ... and was interested to see that the AVG velocity for observations of that species (with lots of data points) was reported as 15.3 inches / sec. And various lower velocity and substrates that correlate pretty well with my (limited) experience for the species I've collected.

Nice to have solid data .... I now have some real design parameters for my next-gen darter tank !!! (No boulder substrate for me, but I'll need some larger chunks than I usually pick up.)

d.d.

Hello Double D, I have not thought of using such field measurements for a tank set up, but it sounds reasonable. Please let us know how that works out for your redlines.
