I bought my first Texas about three months ago from the local Pet Store. He was about 5 cm in length when I brought him home, since then he's been growing at a rate about 3 cm per month. He seems pretty docile for now, I guess. I keep him in my 470 liter aquarium with my three Tiger Oscars, Red Devil, Jack, two Convicts, Black Shark and my Plecostomus.
I have a Texas cichlid, he is awesome. He is very colorful. He does not attack my other fish, a tiger barb, red tailed shark, Kennyi cichlid and a Cory catfish, but right now he is only about 5 cm and will grow to 25 cm. He will hopefully eat feeder goldfish when he is a little bigger. He is definately my favorite fish I have right now, and definately worth the US$5.99.
Just about any cichlids are alright with each other if the tank is at least 1000 liters. Occasionally the red devil and a red terror (festae) cichlid and the Texas cichlids are not a good combination. I've done it in a 780 liter tank and the red devil killed both the red terror and the Texas in a matter of days, because he was a little bigger than the rest of the fish in my tank, although I bought them at the same time. The Texas cichlid is no joke, but have it in with a Red Devil and they will get scales removed quickly.
I bought four Texas cichlids and only two lived due to the bullying of the dominant one. He is very aggressive and has consumed 100 plus white clouds over the course of six months. He grew to double the size of his companion and kept the smaller in a constant state of fear hiding under rocks. As they matured, the more timid one started to come out and grew rapidly. Then things started to change. Their heads became a more bleached out color (quite pretty) and they started to act like they were courting. Well, I woke up this morning to find a tank full of small fry! I love my fish, but canít imagine what I will do with all of them. I always get in this baby predicament with cichlids. They are in a 240 liter tank with a rapid waterfall for good aeration. I feed them flakes, bloodworms, earthworms, and about any bug or minnow I come across. I do not heat the water and they seem to be in the perfect of health. These are great fish, but I would only recommend them for a species tank, and feeding them well means cleaning the tank frequently since they enjoy fresh water.
Tex, as he is referred to has been living in his tank for 4 years. His appetite is huge and his diet is a wide variety of pellets, worms, mozzies, feeder fish...you name it, its his. He's starting to become quite territorial in the last few months as he matures. He's starting to have that known behavior when he attacks fingers and hands. He lives on his own as he has eaten or tried to eat every fish he comes into contact with. He's now just over 20 cm, happy as can be with personality to match. Spits rocks at the glass demanding food or acknowledgement, moves his terrain, and has a nest area. Best fish I ever owned, just need to find the poor lad a female.
I've been fish keeping for 10 years now and the Texas has got to be one of the most beautiful cichlids around. Photos don't do justice to their colours. The simple tip I have with these fish is to keep the tank clean and pH right. No plants - they are prolific diggers. I feed my breeding pair live food such as crickets, earthworms and prawns, boiled peas, dried food - but mostly live food. After all the nutritious food for 6 months my pair grew to 16 cm and my male developed a small hump. I was cut after I woke up to find my prized pair was floating...my heater broke. IMPORTANT: buy the best heater you can find...(sobs).
