I have had Blue Acaras in the past. And when Spencer Jack at aFISHionados in Winnipeg brought in some wild caught youngsters, I couldn't resist, picking out six. They were just over an inch and appeared very healthy and vigorous. I put them in with ten similarly sized Astatheros altifrons young from a recent spawn. They were housed in a 25G cube tank with a sponge filter and silica sand substrate. I decided not to decorate the tank for ease of maintenance. After about a month or so, the 'pulchra', at 1 1/2 to 2" started to show increased coloration and began to interact with one another. It seems I ended up with four males and two females. Yesterday, I noticed one pair guarding a clutch of eggs which they laid on a heater. I immediately pulled the plug so the eggs wouldn't 'hard boil'. Here are some pictures of the really young (and very attractive) Blue Acara parents, all 2 inches of them, doing a great job protecting their very first spawn.
