So I finally got my 55 gal aquarium like I want it. I have 2 crawdads, 2 texas cichlids, 3 corycats, 4 red wag platy, and 5 yucatan mollys. I have a ton of hides, fake plants, 3 bubblers the works. I do a 25% water change a week, and 50% 1x a month. I add about 3 teaspoons aquarium salt, 5 drops iodine at every water change. I feed 2x a day with 1 day off a week. I feed tropical flake, shrimp pellets, with nori, and fresh veggies everyyother day, and blood worms maybe once a week. MY crawdads seem to be molting every week or 2. Is this normal? Am I possibly over feeding? I lost 1 platy to 1 of the crawdads already, which I'm not broken up about cause that little booger kept trying to "kill" my hand and arm when I went to clean the tank. I have worked hard on making this tank look good, and lower the possible aggression levels before they could arise. This isn't just my tank its also for my children. Also my crawdads don't hide except right after they molt. They are always out and about looking for food. Is this normal? All the crawdads I ever dealt with when I was a kid always hid, but those were destined for the cook pot too. These 2 aren't. I don't know what species these are but they aren't the ones I grew up with in and around Louisiana. I can tell you their brownish, and have a tiny bit of blue on their elbows when they were younger. I like them because they have a sociable personality, and want to "challenge" my 3 yr old lol. He loves them. Please give me some insight on these 2 silly things. I'm sorry if this is long but I wanted to give a perspective on how my aquarium is. Thank you in advance for help.
