Week 1 ::
Cosmo perked up so fast after bringing him home and getting him settled. When I chose him I knew that he was being advertised as something unique, but I don't always pay much attention to petstore labels. After a couple of days, and some help from a few members on this forum, I was happy to call him a red pastel rosetail male. Generally I find myself more attracted to the dramatic tail types (halfmoons, doubletails, deltas, etc). My first two boys had been an opaque halfmoon and a blue EE plakat.
After a couple of days his colors became more vibrant, along with his attitude. By far he is the most active and aggressive fish I've owned! He is always ready to flare at me (I think in hopes of earning an extra pellet) and happily darts around his tank. He's certainly not shy. I was delighted and relieved that he appeared healthy, I always worry about petstore fish.
A few days into his new life here I changed his diet to NLS after I discovered that the food I purchased alongside him wasn't the best quality. He didn't miss a beat (or feeding). Though, he does seem to get confused during feedings and needs to be fed slowly or else he seems to have difficulties finding the pellets. He's weird like that.
As for tank maintenance, since he is currently being housed in a 2 gallon, I have been performing 50% water changes every other day to ensure proper water quality. He handles the stress fairly well. The tank is heated to a very comfortable 77-79 degrees. All in all, I'd say he's one happy fish!
