I have:
x1 Ornate (I assume CB) 8" currently and my goal is 12"
x1 Mokelembembe 5" currently and my goal is 7"
x1 Weeksii 5.5" currently and my goal is 8"
x1 Endlicheri Black Volta 6" currently and my goal is 10"
What I am doing to try and get these growth rates is increasing feeding, filtration, and water changes. I am going to start feeding 4-5 times a week with earthworms, massivore, shrimp pellets, tilapia fillets, and catfish fillets. I am planning on upgrading from my 75g (had a 200g but things didn't work out so I'm gonna get something around a 265) and adding 2 eheim 2260's and any other filtration I can get my hands on. And Trying to do water changes 3-4 times a week. However If the cost of conditioner gets to pricey I'll end up dropping to 2-3 times a week.
