Yes I did mean otocinclus (googled it)- it's just the dude was recommending the fish to me and told me the names- I didn't read them (sorry) Well he said they where great little cleaners and it was one per ten gallons. My tank isn't planted- used to be and got slightly outta control so I got rid of a lot of the plants- then all of them died.
What's in my tank is 1 harlequin rasbora, 1 cardinal tetra, and 2 neon tetras- I offered the harlequin and the cardinal to my friend and she's thinking about it, I'll be replacing them with 3 more neons hopefully. I also hope to get a small cichlid (see my 2 threads, "Anything to go with tetras" in the freshwater beginners section, and "which cichlid is best" in the cichlid section.)
I will definitely check out corydoras catfishes.. What do you feed them?
