KittenFishMom Posted November 12, 2022 Share Posted November 12, 2022 Recently I bought several young peppered corys to help with cleaning the tanks. As they are growing, it is clean some are have normal fins and some have very long/high fins. Is they any difference other than the fins between the 2 varieties? Is one more aggressive or hardy? Should I keep they in different tanks when they get older? Link to comment Share on other sites More sharing options...

Males naturally have thinner fins, and I’ve never heard of hi-fin Palaeatus Corys 🤔 Link to comment Share on other sites More sharing options...

Flumpweesel Posted November 13, 2022 Share Posted November 13, 2022 My guess is that it is a bred for characteristics, if you are breeding them then you might want to separate to keep the lines but if you're not fussed I doubt they are. I increased my stock of bronze corys recently with three long fin ones (only ones available) they don't seem to worry about the difference. 1 Link to comment Share on other sites More sharing options...

Sometimes long fin varieties will grow larger but they can easily be kept with standard fin. The only time you would want to keep them separate is if you are breeding for those fin characteristics. Even then, the longer fins can be bred when mixing. I have 2 female long fin cories in a colony of 12 cories total. 1 has high fin in addition to the long fin. My babies come out over 50% long fin and many come out high. Edited November 13, 2022 by Cinnebuns Link to comment Share on other sites More sharing options...
TheSwissAquarist Posted November 13, 2022 Share Posted November 13, 2022 I have found that if the genetics are taken too far, say that a long fin albino Cory is made, it ends up being a weaker fish. Link to comment Share on other sites More sharing options...

My Dalmatian has an ear infection, eye infection, and hair falling off his paws; whereas his mongrel flatmate who does exactly what he does has nothing apart from the cutest eyes ever! 1 Link to comment Share on other sites More sharing options...

AndEEss Posted November 13, 2022 Share Posted November 13, 2022 Why would you buy corydoras for cleaning your tank? Link to comment Share on other sites More sharing options...
KittenFishMom Posted November 13, 2022 Author Share Posted November 13, 2022 (edited) They eat any fish food on the bottom and stir things up out of the substrate into the water for the filters to ca they poke around objects looking for scuds, and knock the "dust" out of the corners and into the water.

TheSwissAquarist Posted November 13, 2022 Share Posted November 13, 2022 They also eat some mulm and add a bit of personality to the tank! 1 Link to comment Share on other sites More sharing options...
KittenFishMom Posted November 13, 2022 Author Share Posted November 13, 2022 @TheSwissAquarist mine add a lot of personality to the tank. I love watching them putter around the tank. Imy young corys are still small, and my camera skills are smaller, but I will try to get some photos. the hifins look like they are pretending to be sharks and the long fins look like they have cricket bat on they fins.
