The Blue Acara is an easy and most beautiful fish to keep for an experienced fishkeeper, or someone new to the hobby with a large tank. They are easy to breed, look after and do not demand perfect water conditions. You can feed them on almost any fish food and they enjoy any live food, my fish enjoy brine shrimp. When breeding these fish, you can encounter many problems like one of the parents trying to eat the eggs, the parents splitting up and fighting each other (happened to mine) and sometimes the parents just don't bother breeding. In my opinion, feed the fish on bloodworms and live brine shrimp because a change in diet may do the trick for breeding, or maybe just turn the temp up a bit. When these fish fight do not separate them! Let them fight it out between themselves, because if you separate them they may never get on together again and fight to the death. You can have much fun with these fish. I taught my 2 acaras to feed out of my hand. If you have the right sized tank for this fish, I advise you to get a Blue Acara.
I have a Blue Acara in with a pair of Convict Cichlids (one larger male and a red-bellied female) and two Julii Cories in a 170 L tank. He's about the biggest I've ever seen at around 13 cm long. I'm puzzled as to how much bigger he'll get in my tank. He devours blood worms and Brine Shrimp, and tends to be the most peaceful of the 3 Cichlids. While being the least aggressive, he's the most intelligent, and tends to be the most animated. He has a personality, I swear to it! He does though, he has a tendency to just float around for no apparent reason. He is very colorful, which I lend to having an expensive high spectrum light, and good feeding. I have found, unfortunately, that cichlids are messy fish! Their water needs to be changed about twice a month, and they have a huge tendency to move the gravel around, at whim. Overall, he's my favorite fish.
I've recently bought three blue acaras for the sake of getting a breeding pair. After removing one of the males because the other pair (male and female) were beating it, they were instantly breeding and they are less than 5 cm long. They seem happy living so far in a 140 L tank with a central piece of driftwood and many plants that don't seem to get eaten except the algae.
I recently bought two blue acaras for my 240 L tank. At first I thought they were a pair, but turned out that they were both males, so I went and bought two more, which were females. I never had any trouble with them being aggressive to my other fish in the tank, I just put a heap of slate rocks in the tank. Immediately a pair formed between them and they started cleaning an area on the rocks for spawning. Just tonight I noticed about 50-80 eggs on the rock and am in much anticipation to see if the fry survive.
I purchaced 5 Blue Acras about 10 months ago, they were very small, 4 cm each. Now my biggest dominant male and most favorite is 22 cm long and 9 cm in height. The rest are aound 15 to 18 cm. I have a successful breeding pair and finally another two have hitched up. I found that I had to remove the fry, as once they started moving about the parents ate them. My tank consists of 3 silver dollars (10 cm), 2 rather large angels, 1 gourami and a silver shark. All these fish were introduced together and have not lost any due to fighting amongst the community.
Just a quick note - I've recently purchased my first Blue Acaras, and have discovered that they jump...and well! It's not behaviour that I've seen mentioned previously, so be warned. Other than that - delightful.
I keep a single male blue acara in a 200 L community tank, along with 14 tiger barbs (5 of which juvenile, adopted from a friend who found them too aggressive), a pair of breeding angels and a 15 cm sailfin pleco. The acara is the most gentle of them all! It has never shown any signs of aggression, and is often victimized by the two angels, although it far exceeds them in size. Perhaps the fact that I adopted this fish badly injured by a Red Devil can explain its timid nature.
