Upgrading To A 29 For A Lonely Reticulated Cory

    The petco "dollar pr gallon" sale rolled around, so I figured it was finally time to upgrade my betta, 3 peppered cats, 2 trilli corys, and ping-pong ball sized mystery snail. Some bacground about the lonely trilli: I bought a group of trillis a while back, but it turns out they had an aggressive internal parasite that caused a wasting type illness. I could only save one of them, the rest died some 1.5 weeks after purchase. In an attempt to make her feel less stressed, I bought her some peppered cories because trillis were hard to find. But she didn't truly shoal with them, so I bought her one trilli on ebay. But now the tank is at capacity, and she still seems lonely. So I know I need more cories in this 29gal, I just don't really know how many. Ideally I would like to add to the peppered cat school, too. But keep in mind there is already a betta and a snail. Thanks guys!

    I found some Trilli species here:

    Not sure how many you should have- I will let someone who has experience with cories answer that.

  3. pumpernickelValued MemberMember

    Yep!! I found some there too, and I was happy to see them in stock. They are usually only available seasonally. Thanks!

    What do you mean with Reticulated cory? Do you maybe have two different ones. One trilineatus and one reticulatus

  5. pumpernickelValued MemberMember

    Nope, sorry. Just some trilli cories and spotted cories. My bad, mistake on the name there.

    Other than the cories you wanted to add, the betta, and the snail, did you want to add anything else?
  7. BetrayerWell Known MemberMember

    Ideally, cories should be kept in groups of 6 or more. 12 in a 29-gallon might be doable, especially since their only tankmates would be a Betta and snail.

    Originally I also wanted some upside down cats, but I would rather my cories were happy.

    I think you will really enjoy seeing their behavior when you increase the size of their shoals. They should feel a lot happier and more secure. It's great that your first priority is their well-being :)

    Another thought...what size tank are they currently in? Is it something you would be comfortable keeping the betta in? If so, you could probably get a group of small schooling fish for the 29-gallon, along with a small gourami (maybe a honey or dwarf gourami). I would stick with a single school of maybe 8-10 fish (tetras or rasboras are good options) because 12 cories will already have a fairly large bio-load.

    I don't have that many $$$, so I'm hoping to only run one tank. Plus my betta seems to like having cories around so he knows how to be a bottom feeder -_- haha
  11. BetrayerWell Known MemberMember

    I understand! That is perfectly great too. Your betta will have a great home with his cory friends :)
  12. pumpernickelValued MemberMember

    So maybe I should aim for 10-11 cories?
  13. BetrayerWell Known MemberMember

    I think it would be okay to get 6 of each type if you would like. That should be perfectly fine along with your betta and snail. Especially because the trilli cories are usually a little smaller than some of the other cories.

    Sounds good!! But my lonely female is huge. Like a mini tank! But more in bulk and height than length...
  15. BetrayerWell Known MemberMember

    Oh that's funny! Is she bigger than your peppered cories?
  16. pumpernickelValued MemberMember

    Well she's definitely taller and more boxy/ triangular. She's pretty big. Like a tank. Of adorableness.
  17. BetrayerWell Known MemberMember

    I wonder if your peppered cories are all males. Males tend to be noticeably smaller than females. Anyway, she sounds adorable! It's very cute how much you enjoy her. I feel the same about my cories. They are very endearing :)
