Oh boy this is my kind of thread I have gone full circle with these animals....
1. Tank- make sure you have a place like a sump or separate tank where that pods can breed heavily. The mandys and other animals will eat them all day and night....YOUR TANK IS TO NEW IN MY OPINION...6 MONTHS IS A RULE OF THUMB...because the pods need to get to a high enough level to feed everyone, make it through your plumbing, and filtration system meaning skimmers, media, socks and what not.... these things kill pods
2. I recommend a separate tank for the mandys themselves... my reason... EVERY ANIMAL IN MOST TANKS LOVE PODS.... they have the natural fats and oils etc. That they need.... my blennies, coral beauty and flame angel gorge on them....everyone looks pregnant and always are pooping lol.... the mandys are so freaking slow and will sit there and starve as the other animals eat all there pods
3. THE MOST IMPORTANT THING...never accept a mandy or dragonet that is emaciated meaning there body and jaws are sunken in.... yes they are alive but once they are sunken in there livers and internal organs rearly recover....meaning mandy heaven and your cash at the pet shop...
4. I have spent a lot of cash to learn about these animals because they are my favorite animals in the trade now.... please listen to me and enjoy your mandys...good luck
5. Your tank can house several mandys I would love to see all four species in a tank your size , BUT they are aggressive toward each other if they dont have plenty of space and hiding spots to claim a territory..... DO NOT PUT THEM IN A TANK WITH A BUNCH OF POD EATERS.....THEY WILL JUST STARVE SADLY.... as a side note.... big tanks like ours tend to have big powerheads..sadly I lost a couple by them swimming to close to the blowers so be cautious....
6. Keep dosing life phyto here and there for the pods to absorb because they don't have true mouths....you don't want them to starve and you have all those crutateans die off in your system
Here is my thread on the subject....
