WOW, we have some touchy individuals here.
I have so many favs. It started out with the Amphs. (RD, Xilo, Sag, Hoga) Out of that group I'd go with my Hogaboomarum, Color, personality, attitude.
Then I would say the Parachromis. I love my Dovi, and RTM the best. The Dovi for its pure strength and size. And my RTM for there beauty, and color.
Festae for the pure beautiful colors, and rarity.
Grammode for its unique look and its mini Dovi attitude.
The Red Devil for its pure nastiness and personality.
Capintis Escondido is absolutely stunning.
All of the Vieja's. (Argentea, Maculicauta, Regani, Synspilum)
Some new additions to my family that are starting to grow on me are:
Umbee, Zonatum, Ornatum, Robertsoni, Naurasatti,.
OK, OK! I'm done, too many favs to choice from.
Wait 1 more on the fav list. My Cren. Lenticulata. Just one awesome looking Pike.
