Sorry for my virtual absence! First, a quick and obligatory "WAAAAHHHH!!!!!" that my favorite magazine, for what I am sure is sound economic reasons, is going to every other month. TFH has been a monthly companion, whether I have been active in the hobby or not, while at school, at sea, or overseas since the late '80s. I will adjust, and I look forward to seeing it every other month for decades to come.
Now on to business...
My little boy's pre-school had 5 x juvenile African cichlids in a 10 gal aquarium. Not good for fish, not good for soon-to-be-traumatized toddlers. We had been considering a Rift Lake tank for years, so we used this an excuse to get going. In exchange for 6 x small rasboras, I took the cichlids and plopped them in a 26 gal flat back hexagon I pressed into service. Equipment on hand included a hang-on-the back power filter rated for a 55 gal tank.. The bottom is 1"-2" of smooth, moderate sized gravel. I also popped in 7 x small clay flower pots. Before taking possession of these guys, I checked with the LFS, and they successfully keep their African in local tap water, which tends to be neutral with moderate hardness. The little fellows are eating the flakes, pellets, and freeze dried foods I provide, so all seems well. I am not normally an impulse buyer when it comes to fish, but time seemed of the essence. Cash is a bit low right now, so I just want make sure I have the basics to keep these guys happy for now. I have a 55 gal I can press into service later, hopefully with a more considered aquascape.
The harder part is the Fish ID. All the critters are juveniles. Two are a lovely lemon yellow (Neolamprologus Leleupi, perhaps?), two are gray with several stripes (no clue); and one is cream with a dark horizontal stripe (Julidochromis sp, maybe?).
I won't pretend the pictures are good, but here they are. Even a ballpark guess as to what I took in will help us along:
The Yellow Fellows (adequate image):

Vertical Stripe Critters (bad image):

Horizontal Stripe Guy (really bad image):

Thanks for your forbearance & Steering Orders!
Aloha,
Eric
