The difference is looks. I have only kept breushowdodoyouspellit, but have been told by experienced fishkeepers they are similar in their needs. This is my second time with them, and I have an expensive observation. The first time I had them, I was only able to get 4, and they were okay, long lived tetras. This time, I got 11 and put them in a 75.
They are the truest shoalers I have ever kept. They stay together even when safe. Their only tankmates are a peaceful pair of Chromidotilapia nana, and the tetra shoal moves together. There's one that peels off to explore for food sometimes, but when food is found, the whole group is called in. When I had 4, they scattered like SA tetras.
I would love to get 10 or more Alestopetersius brichardi, or even caudalis, just to see if the behaviour would be similar. Both of those are beautiful fish I've never had in a large group.
I'm pretty sure I have one female caudomaculatus in my breuseghemi group, because of the large scales. She fits right in. The breuseghemi keep their colours at all times.
Never have tried “Seriously Fish” . If they aren’t in my Innes Book or in TFH - “I know nothing” ( in my best John Banner voice).
I used to 'class' fish by the Baensch Atlas series. Book one had the Innes and Axelrod species, book two had hard to find stuff, some of which has since become standard, and book 3 had rarer species. TFH magazine covered a lot of the new finds - the monthly column I wrote til 2006 was about small fish. It was called Through a Small Window, and had a lot of Baensch "three" fish in it. I never liked Axelrod's books though. He was a dull writer who sounded absolutely certain, and like all of us, he was often proven wrong as people learned and explored more. Innes was a wonderful writer.
