Well, this is my 4th attempt to QT a set of Atlantic Cherubfish pygmy angels for my reef tank. Because of past failures, I have changed things up. Source: My first attempt was diver collected in the Florida Keys and they died of ammonia poisoning (my fault). I then had two attempts from Aquatic Specialties where the fish were obtained from Sustainable Aquatics. After two failures, I have confirmed with others that the pygmy angels from SA just do not do very well. Captive breeding is still in its infancy for many fish and much work needs to be done. These fellows are from Haiti and were imported through Aquatic Sealife. While 1 died in the store, these appear to be in good health. The store ran them through QT including PraziPro (single treatment), methylene blue and Seachem Cupramine (0.5 mg/l for two weeks). The total QT period was 3 weeks. Mating Setup: This time, I am starting with 2 instead of 3. I suspect that the ritual fighting to establish the dominant pair was killing off the third wheel (in nature, there is enough space...in a 20 gal QT there is not). I believe the two "winners" were damaged as a result and this contributed to their demise in QT. My plan was to establish a harem but I am convinced a bigger QT would be required to accomplish that. I think my success will be more probably with just a pair. Tank Transfer Method. My plan here is to use TTM instead of copper. The angels are in QT now as of Sunday evening. I will dose Prazi Pro tonight and after 3 days move them to a second tank. Both tanks were matured over the past two months and I have an additional seed sponge in my DT for the first rotation. I am undecided on a second round of Prazi since the store reports they already had one. I may do so on the 3rd tank. Feeding. I am feeding a blend of Reef Nutrition foods supplemented with EcoSystem Reef Solution. The fish both took immediately to feeding. In my initial observation, there was no fighting between the fish at all. They took together right away. One does take shelter inside my PVC cave while the other takes shelter on the outside. I plan to add a PVC elbow to see if the other will retreat separately or if he (gender assumed ) is guarding. Since I will be doing TTM, I plan to feed them in multiple feedings per day. Perhaps a drop of liquid food hourly when I am home and awake. Ammonia will not be a concern with the TTM and the frequent feedings should help them grow a little quicker. Another concern of mine that perhaps worked against my previous attempts. Photo taken at feeding time this morning. Food recipe is Reef Nutrition Mysis-Feast (5ml), Arcti-Feast (15ml), Beta Brine (20ml), Real Ocean Eggs (15 ml), Tigger Feast (15 ml) & Roti-Feast (5ml) fortified with 15ml of Reef Solution. They will receive about 1 ml of food daily spread out hourly during morning and evening hours (perhaps 3 feedings each). From photo, tank is quite "mature" lol.
