Good morning everyone! I recently set up my new 75g, with plants and new hiding spots and all. I had 5 guppies and a bunch of babies, and added them in the tank with 5 long finned danios and a yoyo loach. I ended up getting a pictus catfish, after doing some research. I should have known the consequences, and now have lost a momma guppy to the little turd, and maybe my yoyo. I got him to eat the fries, and because he seemed super neat. I haven't seen my yoyo in a couple days, and this morning I found a finless momma at the bottom struggling. I'm gonna return the punk tonight. My question now is, what can I replace him with that will eat those babies but will be fine with my adults? I thought about Oscars but I've never had them before. Suggestions? Also, I wanna get some ghost shrimp to do some bottom feeding and I remembered seeing crabs around. Anyone have any experience with those little dudes? Thanks in advance! Hope you guys have a good day!
