I would just stick with your original plan of CB delhezi. With endli, chances are high that you would be forced to sell the bush fish due to predation by the endli.Honestly i thought endlicheris get to big for my tank?
Could i keep a group of these?
So you mean that bushfish attack other bushfish or do they attack other fish in general?
Is it general better to keep Polypterus CB or WC?
Here in Germany you can only get CB Delhezi from the big farms in Indonesia, there is no private breeder as far as i know.
And WC delhezi cost about 100€ apiece.
