Not quite as purple but a purple fire fish would be a more docile purple addition..
also not to turn this thread around on you but have you been testing your water parameters? Seem like you tanks been up barely a week and your adding fish? LR and Live sand help but taking it slow and giving it time to ensure you won't harm or kill any living creatures is always a good thing in this hobby...
Agreed that it perhaps has been a little fast. Parameters (as of today), which have also been tested daily, are as follows:
PH - 8.3, roughly. Definitely the hardest to tell with the test kit.
Ammonia - Reading 0 (was not definitive as of yesterday as there appeared to possibly be a tiny trace) but today it is definitively 0.
Nitrite - 0
Nitrate - 5PPM or 10PPM.
Salinity - 1.024 (with LFS refractometer and my own newly purchased refractometer as of last night and today).
I've been testing every day on all of the above categories even though I have been told that may be over zealous, but I wanted to view the process to see where things went.
On the opening day I put a dead shrimp in the tank along with a bottle of bacteria. Ammonia definitely spiked, though not ridiculously high. It appeared to sit at this level while. Roughly .25-.50PPM. But the color has definitely dropped to 0.
Nitrites never did anything which I found to be interesting but I didn't challenge it. It is 0, and has stayed 0 even to now.
Nitrates, according to the LFS, are around 5PPM. My personal opinion is 5-10PPM, though these colors are hard to tell as the lighting used to view it makes a big difference.
I can definitely agree with you that it is safe to go very slow, but my readings (for the deadly toxins) are 0 with even nitrates being lower than a lot of long-term established tanks. Obviously this could change overnight and bite me in the butt, but I am not against donating the fish back if a major issue occurred. I have donated other fish in the past for more innocent reasons than possibly deadly environments.
