However, I kind of feel undecided about what I kind of tank I should setup & what fish I should get. Right now I have a 29g and a 20g high. I honestly detest these tanks because of their height you don't actually get that much room for your fish and its harder to grow plants. I'm leaning towards buying a 20g long and selling/trading in my 20g high. I'm consider other freshwater species aside from puffers. I have a couple ideas and I just wanted to list them out to see what you guys think. I don't want too interactive of a puffer since I know they'd get bored and I can't always "play" with them. Suggestions kindly appreciated! I'm really all ears for filling my 29g or 20g high or future 20g long. Also, this is kind of off topic but would I be able to "breed" Marble Shrimp in a 20 gallon (long or high)? When breeding fry/shrimp, more gallons = better results? I remember Pufferpunk saying a 20 gallon would be fine for a Congo since they're not that active, but would a 20 gallon high be too small?
Tank Plan 1 - 29 Gallon
FISH: Congo Puffer, no specific color in mind ( I realize its going to be hell trying to find one of these considering I haven't seen one in person in over two years...)
PLANTS: Duckweed, floating plants. Maybe a plant with large leaves so the congo can lay on it every now and then. ( I've read/seen some pictures where Congos nap on broad leaves. )
SUBSTRATE: Black sand.
DECOR: Round, smooth rocks and maybe some driftwood.
LIGHTS: Standard fluorescent. I don't plan on spending much for lights really when it comes to this tank set up since I won't have that many plants.
STAND/ETC: Buy a stand for a 29 gallon and keep the 20g underneath. Maybe breed some cherry shrimp/guppies/swordtail/cichlid fry with it for feeders. Have a dark background. I'd be going for a really dark tank where the plants could really contrast. A layer of duckweed on the top of the tank would make it even darker and maybe more comfortable for the Congo. Hes a lurker and an ambush predator so I guess he could hunt better and I think it'd look really nice in the end.
Tank Plan 2 - 29 Gallon or 20 gallon
FISH: Dwarf Puffers - quite a few of them.
PLANTS: Fake mostly since I wouldn't want to bother with lighting/etc.
SUBSTRATE: Eco-complete, something dark.
DECOR: Driftwood? Rocks here and there.
STAND/ETC: Stand for the 29 gallon. Breed shrimp/snails in the other tank or visa versa. Maybe I could have 29 gallon with plenty of shrimps/snails and some kribs while the DPs are in the 20 gallon. Cost-wise, this is a little out of my range and might take a little more effort considering I'd be setting up two tanks.
Tank Plan 3 - 20 Gallon
FISH: Kribensis.
PLANTS: Low light plants.
SUBSTRATE: Some eco-complete or sufficient plant-providing substrate.
DECOR: Broken pots here and there. Driftwood?
LIGHTS: I'd definitely have to upgrade lights to support the plants.
STAND/ETC: Got a desk. Honestly it seems a little boring since my dad already owns some cichlids. Breeding the kribs sounds like fun since I've seen them (at the LFS) take good care of their young. Could just breed & sell a lot with the 29g and 20g.
I had a couple more ideas earlier but they seemed to have slipped by mind at 1 in the morning. Anyway, thanks for reading and please don't be afraid to comment. I just want someone's opinion on this. I'm really leaning towards the Congo puffer idea since I can see the tank looking pretty nice in my mind (though it might turn out that way in the end!
