BSC - :lol:
Blues are lovely fish but when it comes to intelligence they're the blonde of the fish world, don't you know that's why
they're so pretty
I used to have GBR's but I don't any more, however they are very cool fish and I think Illy-d is on the right track with the discussion topic.
You guys can really turn this into something so why not start off by discussing your methods of keeping them, how you've had the most success, what you would recommend to others, what you WOULDN'T recommend, what do you feed them, what are your water parameters, water change regime, whether you tried something unusual and if it was a success or a failure, have you bred them - how did you go about inducing spawning, what were the success rates, in what parameters did you have the most success/frequent spawns etc etc etc - it all adds up to the shared mine of knowledge....
My female (when I had them)
Here they are with some fry:

I found that the best parameters, or at least those which resulted in the most success (for me), were as follows:
Temp 30C - 86f
I kept them in a 10/15 gallon tank to themselves as they were a strong pair which were incredibly prolific when left to their own devices in this way. If I found the aggression to be increasing (usually about a week into the fry free swimming stage) I would add a few RummyNose Tetra - Hemmigrammus bleheri
, to the tank.
It is very important to acclimatise the dither fish to the tank in this situation as they will be spending a week or two in water temperatures that exceed what they would normally tolerate. I found the Hemmigrammus
to be particularly hardy and they even seemed quite happy in there (metabolism was through the roof so they were eating a bit more than usual), the bright red of their faces a good indicator of their health and the water quality. I would rarely leave them in the tank for more than a few weeks however as it will burn them out in the long run, so once aggression had calmed back down I would remove them to another tank which was better suited to their everyday needs.
Water changes were performed weekly, bi-weekly when inducing spawning, and daily when fry were present. Water changes would be around 50% on average, re-filling with parameter matched water. With fry present and daily water changes it was only necessary to perform 10% changes - this is because we don't want to risk stressing the fry too much.
I had a great deal of success in terms of breeding these fish but I was never in a position to raise their fry - I believe I was breeding my P. taeniatus at the time and so all tank space was chock full. Like the majority, it was not uncommon for the male or female (I found it was usually the female) to eat the fry/eggs, initially they took several practice runs before successfully rearing fry to a couple of weeks free-swimming, but left to their own devices after this the pair would inevitably end up eating them all, every time.
So really to have a strong chance of raising the fry properly, it will usually be necessary to remove them, using a large pipette or turkey baster type implement and then place them into their own, bare bottomed, gently lit tank (if at all - preferably not), parameters MUST be exact in the fry tank - ie fill up the fry tank from the main GBR tank so that there is guaranteed to be no difference in parameters. It is recommended that you give them a good few practice runs to see if they can't pick it up themselves and successfully raise them, so don't edge your bets on spawns resulting in fry, certainly not for the first few attempts.
I fed my Blues on NLS (new life spectrum) as their staple and although not necessary I found it an incredibly strong trigger and catalyst (as with 99% of fish) to supplement their diet with (whole) krill broken up and daphnia when I wanted to really induce spawning.
Spawn sizes would average around 70-100 eggs, out of which 50-70 fry would develop successfully.
That's all I can think of for now. That's my 2c to kick start your new club.
