Today I went to somebody who contacted me this past week. He wanted to get rid of his guppies. I wasn't sure what kind of guppies they were. So, today I've paid him a visit and he gave me a mix of juvenile guppies/endler hybrids. Well, I took a look at them. They can swim in one of my mutt tanks. But I can't really use them for a project. But they're healthy.
