Mystery shrinking and growth

[fishboy1]

Hi everyone I have a question and I'm hoping you can help me. Within 12 months I have experienced rapid growth from some corals while others shrink. does anyone know why this coral is shrinking. This is my blushing sinularia (i'm hoping it is) from 12 months ago.

This is the coral now.

I have no idea why. This is the 1 which has grown rapidly.

12 months later

I think it is a finger leather coral. Idont know if something is off in my tank as my green mushrooms are growing like weeds and out growing my blue mushrooms, my ricordias and 1 interstellar mushroom are shrinking and my toadstool has grown big aswell.

Are they both photosynthetic? Some non=photosynthetic corals need food in the water column and filter feed.

That aside, the location where the coral is at can impact the amount of current flow and current feeding available. Same situation with available light. I don't know what is up in your tank, but if the coral is failing there somethings wrong.

Coral chemical warfare works the same way, with current flow (and filtration in tanks) impacting each location according to the climate found in a specific location.

I hope that helps, it was pretty indefinite and hypothetical.

I have put new carbon in the back chamber, altered the current slightly, increased the light by 10%. I also use reef roids to feed and I use seachem reef plus and phytoplankton. Don't know what else to do really. Wouldn't coral chemical warfare affect the whole tank.

I'm one of the few that love COLT corals. Oddly, in your 1st top pick that looks just like one. I usually can tell after touching it as they are very slimy and have a heavy mucus layer on the coral. Not to question you as them not being leathers but it sure looks like one. And I been searching to buy one for quite sometime. Regardless, if by chance it is a Colt. My experience is they grow rapidly and strip away a lot of the water nutrients with their demand which leaves some coral behind and not able to grow as fast.

Chemistry is aimed at the “other guy.” If it hurt the coral that makes it what would be gained ifeveryone dies.? The chemicals are aimed at the enemy - they suffer allowing the attackers and advantage of growing space, a deep water port, access to the banks of nutrients, light, freedom just like the wars humans inflict upon their neighbors.

I will have to do some checking to make sure nothing is touching each other. Another 1 is what type of water nutrients are been taken cause I could probably dose.
DKH - 9.2
N03 - 22.1
