mbwells Posted July 2, 2022 Share Posted July 2, 2022 Hello everyone! I want to note quickly that I'm *not* trying to sell fish on this forum. Just asking about general avenues I could pursue should I wish to sell the fish at a reasonable price so I could populate the tank with other inhabitants. Barring that, I'd like some general advice on how to swap out an unsatisfactory substrate for something better for my water. I have a 40 gallon breeder with 42 white cloud fish, a number of Malaysian trumpet snails, and 4 Amano shrimp. I have 14 Tanichthys albonubes (mostly gold white clouds, but a few wild type), 14 Tanichthys micagemmae (Vietnamese white clouds), and 14 Tanichthys kuehnei (yellow or lemon white clouds). The fish are maintained in a heavily planted tank at a pH of 6.4 to 6.6 using a UNS Controsoil substrate. I've been dissatisfied with the Controsoil substrate. My water comes out of the tap naturally soft and slightly acidic, so frankly it's not the best setup for where I live. I was thinking about changing out the substrate for gravel with some crushed coral. I have a 20 gallon aquarium with some orange hatchet danios, and I like the setup much better. However, I've been feeling lately that it's likely a waste for me to keep the tank as it's set up. The T. micagemmae and T. kuehnei fish in particular aren't that common, and really would be best maintained in separate species tanks by a hobbyist who is capable of maintaining these populations indefinitely, and my apartment just doesn't have room for that. I was thinking about instead getting a decent size school of pearl danios (Danio albolineatus). I feel terrible contemplating giving up the fish, but I was wondering if any fish keepers here could let me know if there's any options for me selling fish locally at a price that could cover at least the cost of a school of danios. A swap would be even better. I don't know how often fish keepers move fish around. Of course, I may ultimately just keep the fish and change the substrate out, because I frankly feel guilty even contemplating giving the fish up. I don't know if the fish recognize their owners or if they are distressed when they get moved somewhere. Is it possible to change the substrate to gravel and crushed coral with the fish I already have? I have concerns with having the pH rising gradually with the crushed coral might not be good for them. Any general advice on any of these avenues would be greatly appreciated! 1 Link to comment Share on other sites More sharing options...
