How many red eyes would you put with 6-8 buenos aires tetra and 1-2 severums (or in place of the severums could I have 2 convicts in witht the tetra?)
The problem is that the real key to maximizing carrying capacity is plants. Plants+Buenos Aires Tetras = Fat Buenos Aires tetras and no plants. So let's figure this in terms of bioload capacity in Gallons: A 55 gallon tank, not planted, has 55 available gallons of bioload. Severums get up to 8", 2 of them are 16, double that for being big fish, and then round up to 35. So that leaves you with 20 gallons of carrying capacity. BA Tetras get up to 3", so 6 of them will take up just about 20 gallons of capacity (Lower bioload because they're standard shaped tetras, higher because they're both herbivorous = more poop and aggressive for tetras, so 1"/gallon works). That leaves you with zilch. Skipping the BAs and sticking with the Red-Eyes, you could go with 10 to 15 red eyes with a pair of Sevs in a 55.
Personally, if I were going to keep a pair of big Cichlids in a 55, I'd skip the tetras and put in three hoplo cats.
