First off, the largest tank I have ever owned was a 55 (and I have 2 currently), so any analogies to it would be helpful.
I just bought a new 180 gallon tank to move my community cichlids into. A picture is below. I managed to find one on Craigslist for $250 for everything (stand, lights, UGF w/ 6 powerheads + 3 more in the box, and a bunch of misc other things). I know it needs a serious cleaning and that will be addressed over the next few nights and this weekend. The green box on the bottom right is filled with driftwood which also came with it.
Every tank I have ever had used an HOB filter, but from what I've learned from everyone here is that they do not apply to many tanks >75 gallons. I don't have a ton of money to dump into this, so I was curious as to what kind of filtration is necessary? Would the UGF w/ ph's be enough?
As far as getting everything cycled, I would assume it's similar to smaller tanks: Introduce ~10% of the total expected fish into the tank, wait a few weeks (testing the water frequently), then slowly introduce the rest of the fish by adding ~15-20% more every couple of weeks (more or less depending on water quality).
The fish I have in another tank and would be transferring into this tank are:
1 - Black calvus
1 - Masoni Peacock
1 - Ngara Flametail Peacock
1 - Neolamp. Lelupi (firecracker orange)
1 - Yellow Lab
1 - Arcocentrus Centrarcus
1 - Gymnogeo. Meridonalis
1 - Cryptoheros Spilirum
1 - Thorichthys Mixteco
1 - Firemouth (thor. Meeki)
2 - Pictus Catfish
The CA/SA's are all 2-3" and the Africans are 1.5-2.5". I'm expecting all to reach a full grown size of 5-6" but this tank will look seriously understocked even when they are all full size.
Any ideas on any additional fish that would fit well into this tank? I'm looking for fish of compatable size (obviously no 4' eels, or RTC's), that are relatively peaceful. I'm considering adding a couple more pictus cats, another Firemouth, yellow lab, perhaps some female peacocks. Any thoughts?
