So i have been wanting to start a native michigan tank for a while, and now that I am up here in Michigan i thought this would be a good time for it, just as a summer tank. So this tank will only be set up from this June until this August. But then of course it'll be up again next summer, too! So i've gone out trapping local fish from a river near me, and I've caught a 1.5" rock bass, one 1.5" walleye, five 1.5" minnows, a 2" round goby, two 3" bluegill, a 3" rockbass, and a 4.5" perch (sounds big, but hes skinny and kind of a sissy.) That is 21" total, for those of you who don't want to do the math (i know i dont! math in the summer... what?!?) This does sound like kind of a huge load for a small tank, but there is little aggression and none of the fish have died yet. The Ammonia levels haven't been too bad with plenty of water changes, and now most of it is converting to nitrate.
Specs for the tank:
size: 20g High (24"W x 12"D x 18"T, i think)
lighting: Coralife 2x14W fixture for 1.4wpg
filtration: two HOB filters, one rated for a 10g tank and one rated for 10-30 gallons
substrate: local sand and gravel (washed vigorously) over topsoil ($1.59 for a 40lb bag!), which seems to be pretty nice for the plants.
CO2: none (hooray!)
Here is a pair of bluegill that i caught... someone said in a different thread that this one is a male (i can't actually tell to be honest), but the two of them seem like they are pretty flirty, and they follow each other around like a mating pair of GBR's. The play-fighting seems way to playful to actually be aggression to establish a pecking order, it seems much more like they are trying to get together. Do i have homosexual bluegill?? haha probably not.
Also in the picture above, there is an eleocharis-looking plant to the left and an anacharis/tonina looking plant to the right, and i can't ID either of them. I'll try to take some more pictures to better ID the plants.
Here is the other bluegill:
And a rock bass (?):
...and a pile of driftwod i've collected combing the beach. I've also bought some concrete blocks and a masonry drill bit, so i'll attach the wood to concrete and start taking pictures individually of pieces to sell. Maybe i'll get some oak and hardwoods to use, too, so you won't need weight until the wood is waterlogged.
I thought this looked like crappy manzanita... Also, if i recall correctly, doesn't 'manzanita' mean 'little apple'? because there are a TON of apple orchards around here, and all of them have big piles of dead branches and trees that they have cut down to make room for new apple trees. Should i go steal (not really, i'd of course ask for the farmers' permission first) some recently dead apple tree banches and see if any are attractive at all?
