Biotopes

I was planning on changing the look of my 30 gallon Kribensis tank and really like the biotope for Shell dwelling cichlids. It looks clean and not as busy.

My question is does it matter if i change the biotope from one region to fit a species from another biotope ? Kribensis love to hide between the cracks in rock shelves so surely if i stack shells and give them hiding places they wont know the difference right ?

The larger issue is one of water. Shelldwellers should have harder water than kribs. Also, the kribs cannot remain with the shelldwellers on behaviourial grounds, so you might as well move the kribs to another tank (or to the store or a hobbyist if you are getting rid of them) first. Then rebuild the tank.

No I'm sorry if I explained wrong. I'm basically wanting to create my krib tank into a shell dwellers biotope. I won't be putting any other fish in there except my kribs. I know kribs come from the Niger delta and I have the tank creating that look, however I'm wanting a new look and thought maybe I can change the biotope to a different region without stressing the fish.

In this case, I would answer in two ways. First, I suppose the fish wouldn't mind, after all, if they can live with bubbling divers and mermaids, shipwrecks, skeletons, etc, why not rocks and shells? Provided they have something that replicates what they need environmentally, it should work. The dark substrate and plants and branches can be replicated in other ways. But...

Rocks and shells can affect water chemistry, esp shells that raise hardness and pH. This you would not want with kribs.

And, on a strictly personal note, I would never put any fish in an un-natural environment. But that is just me. I do know that creating a reasonably similar environment to that from the fish's habitat does settle all fish better, and to me this makes sense. I prefer being "safe" rather than "risky" with my fish and their health.

I understand. I have had black sand, same pieces of driftwood, rocks and plants in the tank for a year now and as good as it may look to someone that has never seen the set up before im just getting bored of the same "look" So i was wanting to change it to a brighter , sharper setup with white sand, shells, and maybe a moss wall. I may just re arrange the tank so it looks slightly different.

Thanks again Byron

Please don't go down that path to white sand, etc, that would be very bad. Those fish need what you are now giving them. They are happy, and that is what matters in this hobby.

It's nice have multiple tanks, one can have different looks; any chance of a second tank maybe...?

I have 4 tanks at the moment up and running and all have kribensis fry inside, all 1 month apart.. I have stopped breeding them . . . for now. I used my 5 gallon tank to test the white sand/shells and placed 2 kribensis fry and 4 platy fry inside. I think they will be ok in there until they grow. I think m just going to wait till the kribs grow and then change my 20 gallon long into a shell dwelling tank for some multies.
