Stocking a 30 Gallon Native Tank

  • We are currently upgrading MFK. thanks! -neo
It'd have to be a fish I can catch with either rod and reel or minnow trap and I don't think there are any spotfin or steel shiners in my local creek.

I've made the decision, going with a single green sunfish.

You can catch them with both. Simply go to the fly fishing section at your local fishing store and find the smallest hook you can.

Where are you from?

Near Pittsburgh. I love fly fishing, I'm working on tying some for bass and sunfish now actually :).
 

Awesome! I don't have anything against minnows and darters and I actually plan on setting up a 37 tall I got for free from a friend up as a riffle tank them. Only thing is I got a free 30 long and a free 37. The 37 has the same footprint as a 20 long which is why minnows and darters IMO would do better in it than a sunfish would and I'm aiming it get a tank for both. Regardless, next tank after this I set up will be a native riffle tank. Good to know I have them in my creek, I'm hoping to snorkel in it a good bit this summer so I'll have to keep an eye out for them.
 
So I've also decided to get a small brown bullhead since my local bait store said they get them in commonly wih feeder minnows. It may have disease but so may the sunfish since it's wild caught. I'll be growing it out so don't worry about that, starting in this 30, then to my 75, then to a 180. What's my time frame for upgrades and/or if the bullhead grows so fast it starts to see the green sunfish as food?
 
Well I've decided against the bullhead actually since I think it'd be to overstocked even as a growout. I'm up at Lake Erie this weekend at my cottage for a fishing trip and the fishing has been slow so I picked up 6 nice rocks and a piece of driftwood for this tank since I decided to make it an Erie biotope actually. Can someone please tell me if any of these rocks will change ph since I don't want to check the water and it measures 8.4 like Erie is. Also I've always got driftwood from an LFS, do I just need to boil this and it's ready to go or what?

ive never had an issue with rocks and PH. not saying it isnt possible. but if you are going for a native tank, what better things to use than items that came from the place you are tryig to recreate. i would boil the wood mainly to try and remove as much of the tannins as you can. they are not harmful to the fis, but they will stain your water for quite a while. i think that you could get away with a pumpkinseed though. on average, there max size is about 5in.

Really it's dependant on what I catch on the day I'm going out to get the fish :). I just didn't know about the rocks since I just found out Erie has a ph of 8.4 and I'm not sure what causes it to be that high compared to other local waters.
 
you could always set up kinda an experiment. put the rocks in a bucket with water treated just like you would for your tank. let it sit and test the PH from the bucket once a day for a few days to see what happens. i caught my pumpkinseeds with a 2 liter bottle with the top cut off and flipped upside down. i was catfishing at night and in between bites, i would look in the rocks on the bank with a headlight and shoe them into the bottle.
