Initial Testing of the Hydrowizard
Jay Hemdal looks at the Hydrowizard for generating aquarium circulation and flow in large scale public aquarium applications.
New Pike Cichlids from Argentina
Several species of pike cichlids from the Río Uruguay drainage in Argentina have begun to be exported in recent years. The most attractive of these, including Crenicichla minuano, C. hadrostigma, C. missioneira, and C. tendybaguassu, started to appear in 2006. Unfortunately, just five years later these lovely fishes had virtually disappeared into oblivion, despite the successful breeding of what was arguably the most interesting species, Crenicichla tendybaguassu (Big Lip Pike Cichlid), by Matthias Kählig in Hannover, Germany.
All the licorice gouramis of the genus Parosphromenus that are known live in stained blackwaters. Note, however, that blackwaters aren’t really black, but a dark red-brown color, produced in part by peat-like materials but mainly by the decomposing leaves of trees and scrub that grow close to the banks. These dead leaves accumulate in multiple thick layers and release numerous substances, especially humic substances, which prevent any noteworthy population of bacteria in the water. These substances are very important to the health and well-being of the resident fishes, and often even essential for their survival.
Successful Breeding of the Sunshine Pleco
The beautiful Sunshine Pleco is native to the middle and lower Río Xingu. Juveniles and half-grown specimens live in water depths of 3.28–9.8 feet (1–3 m), while adults inhabit the very dark environment of deeper water. To replicate their natural environment, we keep our loricariid catfishes in a darkened room; the only light comes from one open door. Only during daily maintenance and feeding do we turn on a dim light. We are sure that this is a major element in our success, and not just with this particular catfish species. Obviously, it would be impractical for the average aquarist to keep fishes in pitch-dark rooms, but it is worth trying with species that have so far resisted attempts to get them to breed.

Jon Gordon says:Please sign this to support common sense rules in Florida. Ask Fish and Wildlife not to use an ill-advised whitelist of animals that can be kept. All you need to do is add your name to the following statement, "A viable option I support would be a list of prohibited species, which would be a much smaller, manageable and enforceable list than one that attempts to encompass all allowed species.

Bryce David says:To whom it may concern, A whitelist approach to regulating which species are legally allowed to be obtained and traded will decimate fish farms and pet stores. This is not a well thought out approach for combating invasive species release into ecosystems. Best Management Practices have already made inroads on preventing the release of foreign invader species. I suggest a review of those practices and amend them if they are deemed to be insufficient. Sincerely, Bryce David
Edward Moats says:I urge you to consider the ramifications of losing a 172 million dollar industry in your state. I completely support the black list and agree that invasive species is a big concern. However , I feel that this bill is over reaching and will have a negative impact not only On the industry , but to Florida’s economy.
