Did you know fantastic help is an anagram of Planet Catfish? This forum is for those of you with pictures of your catfish who are looking for help identifying them. There are many here to help and a firm ID is the first step towards keeping your catfish in the best conditions.
Interests: large cats-odd balls-I also breed alot of different african cichlid. but my favorite thing is collecting RARE or very hard to obtain fish...
Corydoras trilineatus is just so much more common than C. julii and so it's more likely that you have the former. Telling them apart may not be easy, unless you know exactly where they were caught. See this post.
I would also think it is a trilineatus because the black marks are like little lines and no spots...
But your fish does show very interesting pattern that can make him be taken for a Julii....
Cheers
