Never heard of them before now, found this though:
[font="tahoma][i]"Inhabits black water forest streams. The water these contain is stained dark brown with humic acids and other chemicals released by decaying organic material. The dissolved mineral content is typically negligible, and the pH can be [b]as low as 3.0 or 4.0[/b]. The dense rainforest canopy above means that very little light penetrates the water surface, and the substrate is often littered with fallen tree branches and rotting leaves."[/i][/font][/color]

[color="#040404"][font="tahoma]Sounds to me like they're quite rare to come by:[/font][/color]

[color="#040404"][font="tahoma][i]"The Zebra Acara is an attractive and peaceful cichlid that makes a good addition to a medium sized community tank. It is not often, if ever, seen for sale in aquatic shops, however is relatively common amongst specialist cichlid breeders and on the auction circuit."[/i][/font][/color]

[color="#040404"][font="tahoma]...and therefore are likely to be wild caught (?? worth asking the LFS on this ??), in which case trying to match the natural water parameters would be more important that normal...I'd say steer clear, especially with a newly cycled tank, and one that is only 20 gallons too! T[/font][/color][color="#040404"][font="tahoma]hese fish reach 4" so I'd think the tank is too small for them really in the long run...[/font][/color]

[/font][/color]
[color="#040404"][font="tahoma]Also any level of nitrites means the tank hasn't completed the cycle yet, you need double zeroes really

You may have a pH drop occurring which is slowing down the process...what's the tap water pH?[/font][/color]
