Corries with Jap Hairgrass

**gid** · 14th Sep 2013, 13:53

Bros,

I am hoping to keep 2 or 3 corries in my 1-foot tank. The substrate is completely covered with Jap Hairgrass.

Will this be ok?

Thanks!

I heard that corries are great digger. So you might wanna consider them again.

Thanks bro, but my jap hc is vey matured and compact, will it still pose a problem?

I am also more concerned about the cory's well-being, I heard that they are very particular about the type of substrate/carpet in the tank. I hope jap hg is ok for them...

I am thinking of adding around 3 cory into my 1-foot tank. Any recommendation for a species that is hardy and small? Thanks!

This was an advice from the owner of an LFS. I, personally do not have experience with cory. This is a video which I found on YouTube while googling:

the below was extracted from the web:

Aquarium Decor

Recreating the types of microhabitat the fish have in nature is very important for the overall health of the fish, and will encourage more active and interesting behaviour. The aquarium should have three distinct areas of hiding spots, vegetation, and open areas. Hiding spots can be made from pieces of bogwood, or any decor that creates a subdued and enclosed area where the Corydoras can sit without being harassed by other fish. Vegetation is important and the best types are bushy plants with lots of stems at the base. Cryptocoryne sp. and carpeting plants are ideal, and the Corydoras will enjoy rummaging amongst the base to find scraps of trapped food.
Open areas are also used for scavenging activities, and the most important thing here is the substrate, which should be fine rounded gravel or sand. Sharp gravel will damage the fish's sensitive barbells and mouthparts, and larger gravel is too heavy and bulky to dig into.

Hope that you might find these somehow useful.

Hairgrass with Corydoras is a bad idea. They need open spaces to dig around. If you want a fish that will scavenge on the bottom but stay happy with a hairgrass carpet, try a Coolie Loach.

Hi bros. my hands got really itchy and I bought 4 panda corries! They seem to be doing well with the jap hg, happily foraging through them for food.

But I have another problem. Two have died with their fins broken n torn off... The only other inhabitant sI have in the tank are neon tetras. Do tetras attack panda corries?

**gid** · 12th Oct 2013, 22:20

Or I don't know if this is possible... Maybe the fins and tails got damaged by the hg or the rocks?

Mostly likely is ph burnt. Neon tetra wouldn't have been that aggressive. Rocks and hg is definitely out of the suspect list.

I have pygmy corydoras in my planted tank with hair grass and they don't dig up my plants. Probably, either corydoras hastatus or corydoras pygmaeus, should be fine with hairgrass. And they do look lovely and cute in schools as they swim together in mid water.

PH burn? Hmm, but my other 2 corries are still doing well.

I have never seen the tetras attacking the corries, but they can get very aggressive when feeding and is around the same size as the pandas.

In the long run even dwarf corydoras species will not like a fully carpeted Hairgrass lawn. They are after all bottom feeders and need open spaces to forage as in nature. Some Corydoras will not dig out plants but young shoots may be knocked out of place due to their constant rooting. I had Marsilea uprooted by my C. sterbai in an older setup, and since they had shallow root and runner systems, they were prone to getting dug out.

Young Panda Cory purchased from LFS may be fragile and easily subsceptible to all sorts of diseases. If you did not acclimatise them properly, the juvenile Panda Cory will die off slowly. They are by far the most fragile of all the young Corydoras for sale at the shops. Increased activity from the Corydoras does not mean that they are "happy" with the conditions. Stressed fish do this too. For the time being, please keep an eye out on your surviving Pandas. Look at their gill cover and see if it looks red beneath it. If you spot it as inflamed or their stomachs are sunken, they might be close to death. Otherwise, feed them well because young Pandas can be slow growers. They will appreciate live foods every now and then but for what it's worth, Hikari Carnivore Pellets are taken even by young Corydoras, which nibble on the edges.

Cory and carpet/foreground plants are definitely a bad combination. The cories will slowly but surely uproot all your plants once they find a gap in your carpet.
