Any of the smaller catfish would work well. Make sure there are hides as most are nocturnal and will hide all day.
With catfish really depends on your pick, some can't stand being with same species, some want to be in schoals.
Most people go with 6 juvenile fish. Tho convicts are usually a lot easier to tell male from female. Twice now, first time with common convicts second with the HRP's I only got a male and female and both times ended up with fry.
Ongoing take on Convicts
Get a male
Get a female
Add water
= fry in no time
With swords I would get one male or a whole bunch six or so. I had three male swords in a 6ft 125gal and they fought it out Highlander style till one remained. Having a bigger number of males will spread aggression. A single male works, gives the females a easier time. Female count can depend on the male count. You want at least 2f for each male. If you go solo male get eight or so females.
Plecos if Bushynose get a male and female, they could breed for you as well. If other kind of fancy pleco get one that stays smaller, like Blue Phantom, Orange seam.
Doing this up in a 75 will be a nice size. I would stay with cats/plecos that stay six to eight inch range as adults .
Sounds good, I think I’m leaning toward 5-6 juvenile Sajica, and getting a pair from that then returning the rest. I’ll get 3-4 male swordtails and about 9-10 female. Then I’ll finish it off with a pleco or catfish or two. Is there anything else I could consider, that the Sajica wouldn’t consider a threat?
Btw here’s my tank, what do you think? Look like it will be ok? I’m gonna replace the tall plants with some taller, better looking ones....
