Anyone who follows the blog knows I’m partial to dwarf cichlids since that is what I keep, which includes shellies. If you’ve been reading for a while, you know I purchased some fish way back in the spring of this year. Included in that purchase was a group of five Telmatochromis sp. “temporalis shell.” These are wonderful little fish, but I find them to be extremely territorial for their size. This may be more a product of the small space I’ve kept them in (20g longs), but that’s a post for another day. Though the little fellas only get about 2.5″ long, they just simply don’t like being around conspecifics of the same gender. IMO, they’re more aggressive than ‘Lamprologus’ ocellatus.
Yes and no. Answers to that question depend on several factors. However, for one example of why you should not allow a breeding pair of cichlids to have multiple broods in the same tank, look no further than Julidochromis dickfeldi. Many species of cichlids can get along just fine with multiple generations of their own offspring, especially shell dwelling species. However, some adults cichlid pairs consider an older brood a threat to the newest brood and will treat the older brood(s) accordingly.
