I've had a Malawi set up for a little under a year now. 55 Gallon tank and due to aggression and space issues I changed the stock to a couple male peacocks. I enjoyed this tank very much and recently decided to change the gravel to sand. I still don't know how it happened but I lost my favorite fish today. Containers I had for water changing maxed out while I was emptying the tank's water. I pulled out the old gravel and replaced it with the rinsed play sand but I was forced to doaround a 65% water change because I didn't have enough container space for water. That was last night. This morning I found my fish dead. I hate that because I'm bummed out, that fish was really cool. Now that my favorite fish is gone I'm trying to decide about going the south american route, or keeping with the African. With my tank size and the look of the fish, if I decide to go SA I've decided on keeping a GT or possibly a pair. If I stay with the Africans, they will most likely be 3-4 male peacocks. Need help deciding.
