My 110 Gal Natives

I used to have a few different spps. in my 110 but my WC TX Cichlid tends to thin the herd a bit. Here are some residents:
Spotted Gar

Mexican Tetras (they tend to dissappear with the gar and TX Cichlid around)

My WC TX Cichlid (from a friends ranch near Brackettville, TX)

The TX Male's Ex-Wife (before he killed her)

I occasionally catch a darter that I throw in. I have one that was smart enough to take up refuge in one of the many holey rocks:

Anyone know which spps.? I find them in the Nueces River.
I usually catch them while trying to catch minnows for the gar. I need a bigger tank.
