Fish suggestions?

[TherapeuticVino]

Hi all

I'm a beginner at fish-owning and could do with some advice.

I have a 60l biorb (which I know some people hate) which I cycled etc and added 4 cardinal tetras and a siamese fighting fish. I left them for a couple of weeks then added 2 glass catfish and 2 more cardinal tetras ( as I read they like to live in sixes). Disaster - the 2 new tetras were terrible fin nippers and the fighting fish ended up hiding the whole time. They also started bullying the other fish (the catfish stopped eating) so I removed them and took them back to the shop.

The tank is looking a bit sparse but I'm now worried about what else to add - the tank has settled back to a nice peaceful happy tank again and I like it that way!

Any suggestions? We'd really like to add something bright and colourful...

(Recap, I now have 1 siamese fighter, 2 glass catfish and 4 cardinal tetras)

Thanks!

I think what you have is plenty, the catfish will probably outgrow the tank (i have one pleco in my 60ltr which will need a bigger tank in the future), Siamese fighter fish (if male) don't like much company.

In my 60ltr i have 6 guppies, 4 rummy nose tetras and one bristle nose pleco, my tank is fully stocked.

The glass cats will definitely outgrow the tank and should be kept in a shoal anyway.

I would add to the shoal of cardinals, they should also be in a shoal. You could get another 2 or 3 in there but that's all the biorb can cope with really. If they are scrapping then it's probably because they don't have much swimming room (which is why rectangular tanks are better).

Alternatively you could just keep the betta on his own- you have to be very careful keeping them with tetras as you've discovered, they can be quite nippy.

Bottom feeding catfish will be no good because the ceramic stuff in biorbs is quite sharp and will knacker their barbels.

You can't fit as much in as a normal 60l tank because the surface area is so tiny and the filter isn't up to much.

Sorry for all the doom and gloom, biorbs look lovely but they really are not very well designed for fish so your options are pretty limited.
