So as of yesterday morning, there was just Grün in that big ol' tank. He's about 1.5 inches now. Maybe a little less, it's hard to tell with him swimming all the time.
But then I saw that little F8. They had him in with some danios, and I knew from before that the only put aquarium salt in rather than marine. He was so thin, but he kept buzzing about the tank and coming up to the glass when he saw me. He was picking at the gravel looking for food too. I asked what they fed him, and they said frozen brine shrimp and "sometimes they'll eat the flake food too." I remembered seeing 3 in that tank last week, and one was gorged with food while the other two were very skinny. I figured that the fat one was eating all the food before the other two could get to it. Plus the brine shrimp aren't that nutritious. I couldn't help it, I had to take him! He was so good looking other than the thinness. He was awful light colored too, but mine got that way when I changed tanks the first time.
I brought him home, and I floated him in the tank and gradually added tank water to the bag over like 4 hours or more. The tank water I have is 1.006 with marine salt, so I was a bit worried about his reaction even though I knew they put a high amount of aquarium salt in their tank. The SG for them is 1.003 or 1.004, but it is with aquarium salt so I didn't know how he'd react. I also fed him bloodworms while he was in the bag. He ate a bunch of the bloodworms (I added Garlic Extreme, just in case).
Once I released him into the tank, Grün investigated him and followed him about while the new guy cruised the tank. Grün made no moves to beat him up or nip him, he just seemed curious. I know that I should have quarantined him, but that tank is taken up by my fantail goldfish, and I was pretty sure there would be problems there. The goldfish is fine, he's just waiting for his new pond home to be installed and set up. Anyway, I'm 99% sure that the new guy's problem is just a bad diet and underfeeding. The new guy did darken quite a bit to darken than the normal coloring, and his pattern is very unique. I'll try to get a picture. I fed them mysis shrimp this morning soaked in Garlic Extreme and Gel-Tek parasite treatment just in case.
