FishObsessed Posted September 9, 2020 Share Posted September 9, 2020 Should corydorasbe housed on sand only or is gravel ok? I've seen mixed opinions on this and wondered what the general consensus was here. This is what I'm currently working with: Link to comment Share on other sites More sharing options...
Irene Posted September 9, 2020 Share Posted September 9, 2020 (edited) Sand or round gravel like that should be totally fine, in my experience. Actually, Cory went on a fish collecting trip to Peru and showed that the natural substrate where some corydoras are found is often quite sharp (jump to minute 22:45). Hope that helps!

MickS77 Posted September 9, 2020 Share Posted September 9, 2020 I keep mine on eco-complete and they all have nice healthy barbels. 1 1 Link to comment Share on other sites More sharing options...
Administrators Cory Posted September 9, 2020 Administrators Share Posted September 9, 2020 It’s mostly about general aquarium health and the types of food you feed. Fees things that don’t get lost deep in the gravel and you avoid most corydoras barbel issues. Link to comment Share on other sites More sharing options...
Chandra Posted September 9, 2020 Share Posted September 9, 2020 I went by advice @Cory's advice and had gravel in one of my tanks. My corys had no problems ever and they have been fed bood worms and they do great. 1 Link to comment Share on other sites More sharing options...
Andy's Fish Den Posted September 9, 2020 Share Posted September 9, 2020 I have kept cories on every kind of substrate you can get for an aquarium and have never had any issues with them losing barbels. I think as long as they are well fed and you don't feed small foods that will get down into the gravel or whatever so they don't have to go digging to look for food you will be fine. 1 Link to comment Share on other sites More sharing options...

ccurtis Posted September 14, 2020 Share Posted September 14, 2020 My corys are all on pea gravel that I purchased at Home Depot. I have never had a single issue. I’m not a big fan of sand. Like Cory said in the previous post, just make sure they are able to get to the food without serious digging and they will be just fine. I feed wafers and they are all fat and happy. 1 Link to comment Share on other sites More sharing options...
StephenP2003 Posted September 14, 2020 Share Posted September 14, 2020 I have a range of corydoras (from pygmy to emerald and all sizes in between) on a range of substrates -- nice smooth aquarium pea gravel, finer flourite gravel, eco complete, and the chunky, jagged flourite red. It hasn't been an issue. As Cory mentioned above I do feed wafers to make sure they have easy access to food. 1 Link to comment Share on other sites More sharing options...
Ben_RF Posted September 14, 2020 Share Posted September 14, 2020 I have a few different types all on gravel or planted substrate like ecocomplete. They all are doing fine. I have six panda cories that have been on gravel but now ecocomplete that have been with me almost nine years. They are still pretty healthy.

Ben Ellison Posted September 14, 2020 Share Posted September 14, 2020 I think as long as it's a tumbled style gravel and not like crushed lava rock or something really rough the barbels are fine Link to comment Share on other sites More sharing options...
Skroob Posted September 14, 2020 Share Posted September 14, 2020 barbel erosion is a water quality issue. Not a substrate issue. You can have Corys on sand and still have barbel erosion due to conditions in the tank. You can also keep them on lava rock and have perfectly intact barbels in healthy water. This is just one more myth in fish husbandry. Link to comment Share on other sites More sharing options...
Ken Burke Posted September 14, 2020 Share Posted September 14, 2020 I like fine gravel with lots of plants. Link to comment Share on other sites More sharing options...
