Breeding the T-bar Cichlid – Cryptoheros sajica

Sajica eggsCryptoheros sajica, formerly known as Archocentrus sajica, hails from Central America and belongs in the same family as the popular Convict Cichlid. I first came across this particular species of fish at an auction in Cleveland, where I picked up a bag for about five bucks. In the bag were 8 fish, each about a half inch in length.  At the time I was living in Cleveland, and they all went into a 30 gallon tank. They shared the tank with a 5 inch royal pleco and some neon tetras and rummynoses. I kept the water chemistry stable with a ph of around 7.6 and a general hardness of 6 degrees. The temperature was set at 78 degrees (F). The tank was furnished with live plants, driftwood and clay flower pots. I also added some flat stones, in hopes the new additions would eventually spawn on them.

They grew pretty quickly.  I fed them twice a day, and feeding was very easy. They pretty much ate anything that fell in front of their face. Every other day I performed water changes of about ten percent to keep the chemistry up to par.  By the end of the first year they were each about 3 inches long.

Finally, one day I had noticed that two had paired off.  They had all the others pinned in corners and fearing for their lives, so the following day I baged up the dominated fish, and traded them in for some baby brine and earthworm flakes before they met an untimely death by the newly territorial and greedy pair. Within days I noticed the couple cleaning one of the flat stones. I also noticed that the female’s breeding tube was visible, a sign that eggs are soon to come. She laid about 100 small. tan-colored eggs the following day. It happened to be my day off, and I was excited that she had laid her first batch of eggs, Little did I know that the pleco decided he had an appetite for caviar. The inexperienced soon-to-be parents tried to keep the intruder away, but the pleco was determined to have his fancy meal. The damage done, I relocated the pleco to my African cichlid tank.

Sajica eggsShe had another batch of eggs 3 weeks later. This time they were better prepared, and with no armored, sucker-mouthed egg eaters in their tank, they were on the road to success. These fish are very good parents once they get the hang of it! They guarded their offspring ferociously, even attacking the gravel tube as I tried to clean the substrate. When they were big enough, I moved the fry I could catch to a seperate 20 high. About 50 fry made it to be traded and sold from that batch.

I don’t consider sajicas a very vibrant species, though they are attractive in their own way. They remind me a lot of the A. spilurus, with their shimmering blue eyes. Maybe their most striking feature is the blue throat developed by both males and females as they mature. Males attain an adult size of 5 inches and females about 3.5 to 4 inches. With caution they may be kept with community fish, but they are almost always aggressive towards others of their own kind. I would say the minimum tank size for an adult pair would be a 29 gallon. I would highly recommend this species to someone who would like to try something other than a Convict Cichlid. They breed easily and are really fun to watch as they spawn and raise their fry. If you have any questions about them, please let me know in the comments section!

Corals in Distress – Mass Bleaching Events

Healthy red and green CoralMany stories have come to light through recent years discussing the plight of coral reefs around the world; overfishing, destructive collecting methods, pollution, and ship traffic damage have taken a serious toll.  A number of new studies show that an even greater threat has emerged in 2010, extreme water temperatures.

Earlier this year, the region of Indo-pacific reefs known as the Coral Triangle (a roughly triangular area that encompasses Indonesia, Malaysia, Papua New Guinea, the Philippines, Solomon Islands and Timor-Leste) endured record surface water temperatures. These extreme water temperatures caused a mass coral bleaching event that may prove to be the worst on record. Read More »

Belly Crawler Pike Cichlids – Adapted Predators

There are many specific groups of cichlids that develop fanatics and devotees in the hobby. Some species of cichlids just have something special that keeps bringing hobbyists back for more. Certainly one of those groups are the pike cichlids. The pike cichlid genus, Crenicichla, contains more than 100 species ranging in size from dwarf species of around 3 inches long to large predators that can easily exceed 16 inches in total length. These fish are found throughout South America from Colombia to Argentina. Pike cichlids have long, cylindrical bodies with large, wide mouths made for eating large prey. Even the dwarf species boast a healthy appetite for things that you would swear are too large for them to eat! Read More »

SEASMART – The New Look of Sustainability

Anemone and clownfishNearly a month ago, I was able to represent That Fish Place for MACNA in Orlando, Florida. MACNA (Marine Aquarium Conference of North America), is one of the oldest and largest marine aquarium conferences in North America. Each year you will find new/advanced technology in the hobby, new companies, and of course, livestock. This year was all about LED technology, which seems to be the future of lighting in the hobby.

Amongst the chatter of LEDs was the talk of Papua New Guinea and the SEASMART program. Last year in Atlantic City, SEASMART attended MACNA in the attempt to raise awareness for the need to collect livestock sustainably with an all new approach. Dan Navin, a close friend of mine collected some information on the program while we were there. He made a side trip to Papua New Guinea while vacationing in Australia to check out the operation, a few weeks later. Needless to say he liked what he saw, and is now the SEASMART MAR (Mariculture, Aquaculture, Restoration) Division Manager.

Freshwater Barracudas – Predators with a Need for Speed

The word barracuda immediately conjures images of a sleek and powerful fish with a mouthful of dagger-like teeth. While most people associate the name with large, open-water marine predators, it is several different species of freshwater fish also carry this as their common name. The majority of these come from the genus Acestrorhynchus. Read More »
