Stocking ideas for new 75g severum tank

[Sonofthunder]

Getting into the hobby again after a 5-year hiatus. Last tank was a 90g with a silver arrowana, 2 green severums, 2 firemouths, and a pink convict. Established successfully for over 2 years.

This time I've picked up a 75g tank and would like to focus on severums as my main species, which ended up being my favorites last time around. Really loved their personality, and I look forward to seeing what they're like outside the shadow of an arrowana. How many would you stock in here?

I'm debating whether to stock severums exclusively, or if I should add some additional tankmates that would complement them. Ideas? I've always admired the species with large forehead lumps, like the midas. Would Anything like that get along with the severums? Anything else I ought to consider?

My filtration right now is a Fluval 306. How many fish should this support? I plan to start with juveniles and can expand the filtration as they grow, if needed. I'm new to the canister filter...my old tank had a wet/dry and I never had any water quality issues. So tips or suggestions on filtration in this tank are appreciated. Thanks!

Hi there, glad you decided to come back to the hobby!

I think your 90 gallon tank back then was not adequate even for the silver arowana alone. I don't think putting a midas with a severum in a 4 foot tank since midas/red devils/midevils are infamous for excessive aggression. You may want to consider a single midas with gravel, driftwood and decorations as tank mates. They make great wet pets and are very interactive.

You may fit a severum and a male convict (it gets a hump too) in a 75 gallon tank with some dithers and target fish, depending on aggression levels.

Right now I have two red severum with 4 Honduran red points. They look great together and are both on the more mild side. My platinum HRP looks like minni midas I think. This is an older pic his hump is bigger now, although they never get humps like midas. If you stay under stocked and have fish with similar aggression levels you will really see the personalities come out.

The firemouths and passionis are no longer in the tank.

Thanks, I like these ideas. To clarify, I realize a Midas is too big to coexist with severums in this tank. I was looking for some suggestions on something that might be similar but smaller. I like the convict idea. I am somewhat limited in the options available to me here in Alaska, so I'm not sure if there are any Honduran red points to be found.

What sorts of dithers/target fish might I consider? I've read that tetras might be a good option. I'd like to stick with south/central american species.

Yes, my arowana was a juvenile. I had him until he grew to almost a foot, then sold him to someone with a 180-gallon.

HRP's are hard to find in my area to. I ordered from Jeff Rapps at tangled up cichlids. If you go with cons I would do a single male or single female. if they pair up the become quite aggressive and will get more fry than you know what to do with. You could also look into rainbow cichlids they are on the mellow side.

Almost any tetra will work. I like lemons but diamonds, Colombians, Buenos Aires, would all work. Cherry barbs would be nice as well.

You could also just stick to a trio of severums and leave it at that.

Severums get to a decent size so I would keep smaller mates. HRP's might be a little aggressive for a mild mannered severum, but it could work. SD's or something active along those lines would be my go to.

OK, so my current long-term idea is to have a pair of severums, a school of about five large tetras (colombian redfin?), and one male convict. Should be fine according to aqadvisor.com.

So the question is, since I'm starting with juveniles, should I overstock to begin with and thin out as they grow, or would it be better to start with the same numbers that I hope to end up with?
