So, I've recently developed an interest in breeding BN plecos but I don't really like the idea of a species only tank. I'd like to keep other things in the breeding tank with the parents and fry but I'm not sure on what would and would not eat the fry. I have not started setting up this tank, nor will I for probably a year or so. I am about to start moving across the country so I will not have much time for fishkeeping for awhile, but in my head I have been planning out what I would like to do with this tank that I plan to set up in the future when I am able to. The tank itself will probably be a 40G breeder, I may go a little larger depending on stocking plans and such but I like the size of the 40G breeder. I really like mollies so I would like a couple in there, I'm thinking just three females, I just like their personalities. If mollies would eat the fry then I'm open to suggestions of similar fish. I'd like some sort of small schooling fish. I'm very interested in celestial pearl danios, but as they are on the more expensive side I may end up going for something a little cheaper. I'm thinking 8-10 small tetras or danios. I'd like to point out that every tank that my dad has ever had in our house has had neon tetras in it and I honestly do not find them interesting at all as a result. Now that I will be out of my dad's house and the tanks I set up will be my own I'd rather not have any neons, but any other similar sized schooling fish will probably work. I tend to prefer the very colorful ones. My boyfriend really likes the dinosaur bichir at Petsmart, I believe its proper name is senegal bichir? Would one of these be okay in a 40G breeder with fry or would it eat them? If it would not be okay then that's fine, just thought I would ask. We do really like the fish that are shaped like this though, long and rope-like. Would there be a similar shaped fish that would do okay with fry without overstocking the tank? I would also like a few shrimp, I'm thinking cherry shrimp, would they be alright with this stocking setup? If not is there another shrimp you would recommend over cherry shrimp? Finally the BN plecos, I'll likely try and grab just two of them. A male and female, one albino, one normal colored, doesn't matter which is which. I've put my stocking plans into aqadvisor and this is what it tells me, 2x BN pleco 3x molly 10x CPD 1x senegal bichir 5x cherry shrimp Stocking level is at 72% As far as I can tell there is no way to tell aqadvisor that you plan for there to be fry in the tank, so it does not give me any red flags as to if the bichir or any of the other fish would cause problems. If the bichir would eat fry, would I still be likely to have some fry survive to a safe size before the bichir ate them all if I were to give them plenty of hiding places? I can accept losing a few of the fry to other fish, but I would like to have some of them reach adulthood. I would likely end up trading fry in to LFSs for store credit once they were big enough. So to sum up all my questions, 1. Can I keep mollies with BN pleco fry? If not, what is a similar fish that would do better with the fry, if one exists? 2. Can I keep CPD or similar fish with BN fry? 3. Can I keep cherry shrimp with BN fry, as well as the other fish in the tank? If not, is there a different shrimp better suited to this stocking setup? 4. Can I keep a senegal bichir with BN fry? 5. If it would eat the fry would some fry still survive if I were to give them plenty of hiding places? 6. If the bichir just won't work, is there a similar shaped fish that would be better? I think that's all my questions for now, what do you guys think?
