    Random Apisto

    I agree with Frank. The 1st 2 photos show a male brevis-group species, but I'm not certain that it is A. brevis, which should show a dark anal spot. It could be a young A. personata? Time will tell if the dorsal fin develops. The 3rd looks like a young male A. elizabethae to me, too.

    A question of filtration...

    Looking at your conductivity (263 µS/cm) and total hardness (36 ppm) I would call this water moderately soft. Looking at the beer brewing Ca hardness (14 ppm) I believe that about half of the total hardness is from carbonate hardness. I'll leave the water experts to correct me if I am wrong.

    Apistogramma sp miua - sexing

    "really small" = immature (usually). If not sure, give the fish a month or 3 and see how it develops.

    Excessive Aggression between my juvenile pair of A.Borellii.

    A 10 gal tank can work - if you're an experienced apisto breeder and willing to risk loss of one of the "pair". Otherwise a 15 would be the minimum that I'd recommend.

    Gender signs?

    Spawning age really depends to some extent on how fast one 'pushes' maturity (temperature, feedings, water quality). 4 - 8 months is commonly reported.

    Apistos from Rio Xingu

    Several species have been found in the upper Xingu drainage recently, like A. kullanderi, A. flavipenduncula, and A. eleutheria, along with forms of A. taeniata-like species from the Rio Curuá, a tributary of the Rio Iriri. Interestingly most of these fish were found by survey teams evaluating...

    Gender signs?

    Females of domestic strains of A. cacatuoides often exhibit color and fin extensions typical of males, so I hesitate sexing these young fish.

    Apistos from Rio Xingu

    IMHO the Belo Monte dam has affected ornamental fish collecting in the area. We see occasional species from the lower Xingu like A. cf. agassizii and A. sp. Xingu, but we don't see species that were collected from the area around Altamira. Two that I once had were A. sp. Blauspiegel (A 230), an...

    Quick A. Caca Sexing - Female?

    Looking solely at the long tips of the unpaired fins, it appears to be a male.

    Help ID Apistos I caught near Leticia, Colombia

    The bottom photo is definitely Ap. pucallpaensis, but the top one? Prossibly A. agassizii. TomC and I collected the same area in 2008 and found the same species as did you (except Ap. pucallpaensis).

    ID confirmation: A. ortegai 'pebas'

    One word: marketing

    Laetacara chasing issues.

    This is typical cichlid territorial aggression. You have them in too small/open tank right now. You could remove the most aggressive fish, but the next most dominant fish would take its place as aggressor.

    ID confirmation: A. ortegai 'pebas'

    Looks like A. cf. ortegai (Pebas) to me. It most closely resembles the color form in the photo by Koji Yamazaki in Matsuzaka's 1996 book "South American Dwarf Cichlids".

    Ivanacara Bimaculata

    The I. bimaculata have 2 benefits with regard to successful reproduction. They are in a large aquarium that is decently aquascaped and the pair will both defend the area around the fry. If they succeed, great. If not, I'd house them in a separate breeding tank.

    From experience: if the fish come in, in really bad shape - breathing heavily and gasping at the top of the bag - just throw them into a quarantine tank without acclimation. Most wholesalers do this - and hope for the best. Otherwise I use a slow drip method.
