About Christy Expertise I can answer some questions regarding freshwater fish ranging from their care to diagnosing common diseases or problems with the fish. I can also answer questions regarding the care and maintenance of an aquarium. I haven't had much luck with live plants, so can't help in that area very much. Not real good with explaining salt water or brackish set ups too well either. Also regarding goldfish, I have some comets, and have a little experience with them but mostly just general info on them. I AM NOT THAT FAMILIAR WITH ANY OF THE FANCY VARIETIES OF GOLDFISH. YOU MIGHT BE BETTER DIRECTING THOSE QUERIES TO AN EXPERT MORE FAMILIAR WITH THEM. If I can't answer or don't know something, I'll let you know, so don't be upset if I reject your question, I'll always explain why. I would just rather not answer then give an answer I'm not confident about.
Experience All personal, first hand, general fishkeeping experience. I've had fresh water aquariums now for about 7 years. I've had tropical/community fish tanks, African cichlids, South American cichlids, brackish water puffer fish, and a lot of other varieties in between.
Education/Credentials None, all personal experience
Question I have a 30 Gallon, aeration, powerful filter and live plants. It is understocked at the moment. I have 4 cories, 1 oto, 5 glowlights, 1 black neon and 2 neons. Three black neons died and 4 neons died when i had all the fish in a 20 gallon.
I want to add 4 more black neons, 5 neons, 7 rummynose tetras and a black tailed shark.
This would seem overstocked but would the tetras affect thw water parameters because they are so small? I do 35% every four days so i do water changes and I love my fish.
Thanks Jack
Answer Hi Jack
You know, I hate to say neons don't count because they're so small, but really, they won't have too much of an affect on anything. I would probably go ahead and add the regular neons last though.
Otherwise, sounds fine to me. Just add the fish slowly, a few at a time, wait a week or so, then add a few more to allow the beneficial bacteria time to catch up to the extra fish.
Water change schedule is good also! Good luck! Let me know if you have more questions.
