I was at a presentation where Dr. Loiselle said none of the Tropheus would breed outside their group. It was a few years ago. Has he changed that part of the talk? I don't mind raising up different easily distinguished fry together, but when they get to be breeding age, I want single species tanks, even after hearing the doctor.geoff_tropheus said:Sp.REds are the absolute worst at making Hybrids, they are not safe mixes with anything other than Duboisi type.
Anytime you have them mixed, you got to examine all your fry really close, or you'll find your self in trouble with Hybrid fish that got to be destroyed or extremely isolated.
Please forgive me for not knowing who Dr.Loiselle is, but I can tell you in keeping Tropheus for 11 years now, that sp.reds are the worst hybrid makers, and all tropehus but Duboisi have potential to make hybrids with other Tropheus, that is as long as you do not mix two different Duboisi types. Duboisi is the only safe mix.Mcdaphnia said:I was at a presentation where Dr. Loiselle said none of the Tropheus would breed outside their group. It was a few years ago.

It will be interesting to see that if he has changed his mind, if he remembers his earlier position on Tropheus hybridizing. Certainly enough has happened with all the new varieties sort of filling in the spaces between earlier known types and possibly natural hybrids to justify a new opinion.24Tropheus said:Its possible I will be able to talk to Dr. Loiselle on the 12th or 13th of April, BCA Convention at which he is speaking. Maybe I will get a chance to ask him what he thinks. :wink:
I have heard the same thing for years, andrugger said:Thanks for the help. I had heard one from each group, but I won't mix them now. I sure don't want to have to distuguish between fry and cross fry.
Great summary! I've seen his presentations at clubs and conventions several times, but not in the past few years. I doubt if he is still presenting that information in person, but what is published in book or magazine form will still be influencing those who don't consult newer resources too.geoff_tropheus said:In my experience gained by keeping them for over 10 years, reading every book/magazine on them I could find, reading countless articles and postings in forums on the net on them, and personal discussions with other keepers, importers, and exporters this is what I know about Tropheus to Tropheus Hybridization.
Duboisi is 100% safe as long as its not with another Duboisi type.
Annectens & Poli are safe with the other types, but stay away from each other, or anything that has heavy bands.
Brichardi is a little safe with the other types, just make sure the color is as different as possible and definately away from other brichardi, annectens, or poli types.
Kasabae(rainbow types) & moorii (sp.red, sp.black, non-rainbow types) - dont mix these types with the others unless the color is as far different as possible. Still even then it is risky. Very High risk if you mix two of these types together.
Sp.red is the very worst at making hybrids, it is always best to keep reds by themselves.
I have kept Rutunga (sp.black), Duboisi (duboisi), and Katoto (kasabae) since 2002 in the same Aquarium and never made a hybrid fish.
I have kept Lupota and Ikola together for 2 years and no hybrids. BUT..I worry about it daily. I have seen numerous Ikola Hybrids with Cherry Spots, Chimba, Chilanga, and Kachese.
I do believe the best way to keep the fish is a single variant in a 6ft aquarium of about 30 fish. If your going to mix two Tropheus types, get Duboisi, and then the other variant can be any type you like. Otherwise, just keep one type.
I hope one day to meet Dr. Loiselle, if it was 10 years ago he made those statements, A LOT has changed in keeping Tropheus during that time. I just hope he is still not presenting that information.
Take care,
Geoff
