75g stocking

  • We are currently upgrading MFK. thanks! -neo
I have a 10" A.crassipinnis, 8" Pink tailed chalceus, 2 Pictus, and a 5" BN pleco in a 75G....nitrates are 10ppm per week. I do 50% weekly changes. IMO the suggestion that any fish over 7" is too large for a 75G is a bit on the low side. I have seen many people successfully and properly maintain larger fish in this size tank up to the 13-14" point without issues. The fish appeared "happy" and the tanks were easy enough to maintain. Certainly larger is better but personally I see nothing wrong with a 75G housing a fish up to this size with adequate upkeep and aquascaping to maximize the space.

I personally do not intend to upgrade my own Jaguar to a larger tank until/if he gets over 12-13"....fish is right at 8" now and nitrates are 5-10ppm per week and the tank is not planted. I also only do 1 50% WC per week. There is a lot to be said for not over feeding and having a good filter system.

I believe Nannacara would be perfect for that size tank.
Whether or not South American's would thrive in your pH, is another matter.
Those west of the Andes should have no trouble, and the species from Uruguay are also comfortable in harder waters, its just some soft, black water Amazonian species that could be negatively effected.
And it may only be wild caught that may end up with HITH and other chronic maladies.
Adding tannins could also save you some grief for black water SA cichlids.

Could you give me some examples? Do you think I could setup a breeding colony with a dwarf cichlid? 2-4 pairs maybe? I've always wanted black water and I recently bought peat because I was going to experiment with it.
 
Apistogramma cacatuoides would be the easiest one to get that would do well in harder water. Comes in many different color forms. I know a couple of aquarist that have loved having 125 gallon apisto colony tanks.

I would be interested in that. Definitely an option.

CB Bolivian Rams are about the hardiest SA-Dwarfs out there, but African Dwarves like Jewels are incredibly tolerant, and Kribensis are somewhat tolerant of PH and mild aggression.
 
Bolivians aren't my favorite, but I woundn't opposed to them. I already have Kribs that have bred in my 40g breeder.
 
To help you guys get a better gauge on my water, my PH is 8.0, KH 89.5, and GH 179. This was water out of the tap in a bucket for 24 hours with an airstone, so it's as accurate as I can get.

I'm not too familiar with those.

Here's a link to the family tree, best advice I can give you is copy/paste a species name and type "Images" after it. Google away, i'm sure you'll find somethings you like....I believe most stay under 8", but Cichlasoma has been a "wastebasket" Genus for classification for years so there may still be a few big ones in there
