Thinking About Getting Some Corys, But Need Some Advice

[GoldfishAttentionSpan]

I currently have 6 danios in my ten gallon. The tank has medium gravel, with large smooth river rocks in the front and a cave made of slate in the back. The danios will probably move to the 30 gallon that I have, and I was thinking about getting some corys to put in the ten gallon, but I need some advice.

1. Is ten gallons too small for corys? If not, how many would be a good number to get? Are they more happy in groups, and if so, what is the minimum number for a group? I am wanting to put some other fish in the tank, but I am not sure what kinds yet.

2. Will different species of cory school together? (Meaning, if I were to get five, would it matter if I got three pandas and two bronze, or if I just got 5 pandas?)

3. I will change the smallar gravel to sand, but I would really like to keep the larger rocks. The cave takes up a good portion of the aqarium, and I am not sure if the edges of the slate would injure the cories. Would it be ok to keep the cories? I don't think the river rocks would bother the cories, as they are smooth with no edges.

4. I am planning on covering the slate with java moss and the glass jar with riccia. Will cories bother these plants?

Thanks all, and sorry for all the questions!

1. A 10 gallon will be ok for some of the smaller species of cories, like the ones that stay around 2.5". The bronze will probably get too big for a 10 gallon and will probably not be too happy. Cories like to be in groups, the bigger the better. I would say a min. of 3.

2. Some people say they will, I say they will some, but not that much. In my experience, they stick with their own species.

3. I still think sand is the best substrate for cories. I have slate and rocks in all my tanks with no problems.

4. The cories should not bother the plants.

Hope this helps

Bronze cories get to 2.5" or 3", Barracuda.

Bronze cories get to 2.5" or 3", Barracuda.

I know, they get up to 3" and in my opinion, they wouldnt be as happy in a 10 gallon as they might be in a 20 gallon. They might like when they are young, but C. Aeneus is one of the bigger Corydora species, just in my experience with them.
