trough

My Dad gave me their trough that they used to use for their horses. It have 2 cracks so he told me I could have it for free if I repaired the cracks. I have patched the cracks and it's held water for over 2 weeks now. It's not the prettiest patching job I've done but I'm using it as backyard...

Should I stock it with feeders or just a few cool fish? It'll be outside and I live in Texas so it'll have to be a pretty hardy fish. Happily married Mommy of 3 babies, 2 fur babies and 15 gilled babies
