75g stocking

  • We are currently upgrading MFK. thanks! -neo
Even a Severum is too big for a 75g?

A few months back I was looking into Salvini's randomly and from what I read they can be hard to pair up due to their aggression? Excuse me if that's the case with all aggressive fish but I'd like to clarify. Would it be impossible to breed anything SA with my PH? I think a Blue Acara pair with Silver Dollars would look very nice.
 
A single severum with dither fish would be fine for a 75. The acara pair and silver dollars sounds good but you have to remember most silver dollars get big, so that may be a problem...

Even some of the smaller silver dollars don't do too well in 4' tanks... Damn darty, jumpy bastards haha.

I would get spotted silver dollars. My concern for keeping SA fish is will they be fine with a PH of 8? If so, would they spawn in this PH?
 
I will disagree with many of the others who have commented here, I think most of the fish your list get far too big for a 75 long to live comfortably long term. To me anything over 7.5" as an adult is too big.
Most of the fish like Parachomis or Vieja need a minimum 6ft tank.
The 2 on your list I agree with are Thorichtys and salvini as far as Central Americans go, but with salvini, a pair would probably be too much, because they get really aggressive in small tanks.
Oscars also get too big, unless you plan to do daily water changes, and daily filter cleanings. To me an oscar in a 75 is like putting a Great Dane in a bathroom 24/7, and if you do weekly water changes, it would be like letting the Great Danes krapp build up for a week without cleaning.
The fish I would suggest are cichlids "not" on your list like the smaller Cryptoheros species.

Cuban or green terror out of your list. But look at hemichromis elongatus.
 
duanes duanes , what is your opinion on nannacara anomala? I wasn't really wanting to setup a planted tank because I don't have good enough lighting. What small cichlids could work well as a breeding colony?
 
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.

GT would be fine - males get 10-11" in extreme cases, but more commonly 8-9'' and I never seen a female over 6''. 48" X 18" fit the formula; 4X the fish length for length of tank and 2X the fish's length for width of the tank. They are also one of the few SA that will thrive in higher PH as long as he does a 50% weekly
