New Fish – Severums

Got new fish yesterday: 6 Severum cichlids (and a Siamese algae eater).

This has bee a very long time coming. Not only have I been thinking of taking my tank in a new direction for the last couple of years, but trying to keep some of the larger cichlids is something I always wanted.

Going for Cichlids

Why? Well, if you know nothing about fish keeping but hear or read about it, you quickly note the cichlid hype: Large, beautiful fish with interesting behavior and lots of attitude. Generally not too demanding, as long as the tank is big enough and the water is clean. “Generally”, I write – there are some notable differences : )

So it is natural that keeping cichlids are on the bucket lists of many fish keepers (and to many it becomes the end of one bucket list and the beginning of a  new cichlid-centric one).

In my case I have been circling the issue for a long time, trying out various smaller species with varying degree of success (mostly low). A key challenge has been either a poor choice of species or water conditions. My tap water has pH 8 and hardness 22 dKH, which does not work well with South American fish, most of which come from acidy, soft waters. South American dwarfs like Apistogramma and Rams have had short, while kribs have fared better (even spawning twice in my large community tank). But my first feeling of succes was with the cupidos I have kept for the last four years. They are wild caught in Peru, but have  done quite well (I have lost some, and some may not have grown optimally due to periods of less-than optimal water conditions). The difference may be in the food. Before the cupidos I fed mostly flakes, while the cupidos have been fed alsmost exclusively frozen food. So I could have revisited the dwarf species once more. But then again, there are other things on my aquarium bucket list.

Why severums?

I was looking for fish that is

  • large enough to be the centerpiece(s) of a large tank – which rules out the dwarf cichlies: I want a fish I can watch from the sofa accorss the rtoom, although I don’t need a 50 cm wet pet.
  • one that that isn’t totally mainstream, ruling out Scalare and even discuss (so that visitors ask “whaht a beutiful fish, what is it?” instead of “oh, you have discus too, don’t they come in all sorts of colors?”)
  • one that is able to coexist with other fish and don’t necessarliy eat everything green – ruling out many otherwise beutiful and interesting species. Maybe later (the convict is on my list)

Out of those criteria came my list of usual suspects:

  • Firemouth
  • Blue acara
  • Severum
  • Nicaragua cichlid

all of which might fit my criteria, but reading sources on the internet I also know that milages vary. Regardless of the choice, the other fish in the tank may or may not be fine and the plants remain. There is only one way to find out.

In the end it came down to what was available in the local fish store. There were severums (H. nonatus and H. efasciatus (wild caught)), (Electric) Blue Acara and a couple of Nicaraguans. No Firemouths. Since I want a small school to start out with and am no big fan of culture forms like the Electric Blue Acara, and since my latest good results were with wild caught fish, the choice was clear:

6 Heros efasciatus ‘Rotkeil’ ‘Rio Yacali’

It will be interesting to see how that plays out, time will tell.

(As for the algae eater: Great fish for doing just that – highly recommended.)

About Fish

As written in ‘about me‘ I like to care for my fish 1.

After a few years of low activity (little children…) I expect to gear up now, and expect there will be some stories worth sharing too. Therefore this introductory post, similar to my first about gardening.

My interest in aquariums goes back more than 30 years. I am not sure how it started. Perhaps a visit to the (now closed) Fyn’s Akvarium, perhaps a visit to a pet store or maybe seeing an aquarium at a friends house. I can’t be sure, but I remember being very excited – reading every book in the library and making scale drawings of the fish I would one day keep. Then I got my first tank,  set it up and got it overstocked with predictably bad outcome. My first computer arriving didn’t help. After a few years I gave up.

Still, the interest never vaned entirely, and in time realized how I might avoid the pitfalls that stopped me the first time: A bigger bucket for water changes, being able to go to the pet store on my own, better finances (not that aquariums ever need to be a costly hobby)…

Time passed, I kept thinking about it and in 2005 I finally decided to do something about it. I had just finished some years of evening school and my wife was going to work abroad for a while. I started with an 85L tank (because that was the size of my first tank, so I could reuse equipment), but soon I was hit by multiple tank syndrome and I soon had six tanks in a one bedroom apartment, breeding several species.. When my wife returned home the the breeding tanks were emptied, and when we moved into our new house they were filled again.

With a larger house there was both room for a larger main tank in the living room, as well as a proper fishroom for more experiments and more breeding. Since then the fishroom has been re-purposed for baby stuff, so I am once more down to one single tank, a 530L tank housing a planted South American community.

Volume: 530 liters (129 Gal)
LxHxW: 160x60x55 (63″x24″x22″)
Water: PH= 8; hardness 22 dKH

Stocking list (as of Mar 18, 2016):

  • 6 Biotodoma cupido
  • 5 Platys
  • 13 Rummy nose tetra (H. bleheri)
  • 6 Three-line corys (C. trilineatus)
  • 2 blue gouramis
  • 1 silvertip tetra
  • 1 black ghost knife fish

This has been a stable setup for a while and it is time for change.
