I've been reading the forum quite a bit - it seems to pop up everytime a google a plant question! I have some of those but I want to get an issue I have with the other inhabitants solved before I start on them. This is a sort of half shrimp/half fish question, so I hope it's okay to put here.
I've got a 75l tank (aquaone 510) with plants
, 2 amano shrimps, 3 Kuhli, a pair of cherry barbs and a colony of cherry shrimps. It's been running about two years but I have a couple of issues.
I started with two cherry shrimps and they grew up and produced a lot of little cherry shrimps. The trouble is the offspring don't seem to be growing very big. The original two (which passed away around the 18 month mark) were about an inch or so long but the biggest youngsters (about 10 months old) are still only 1/2". They grew quite fast initially and I passed some on to my parents and sister and they grew up. They seem to be breeding despite the size and I think I currently have around 20-30 between 5mm and 1/2".
Could anyone suggest why the aren't getting full size? The water tests okay, are there too many for the tank? I don't feed them specifically but I think they eat the fish food (I have sinking pellets for the Kuhli) and they seem to spend most of their time plucking away at the javamoss and plants.
I'm not sure if/how it's related but I have a big issue with fish, any time I try to add a couple more I tend to lose half what I put in over a couple of weeks plus a couple of the existing ones. Hence, I only have 5 fish. I can't work out the cause though, the standard water tests seem fine, the shrimps aren't affected (and I thought they were more sensitive to water problems), I'm using the same water (RO) as the rest of my family and buying from the same suppliers. I haven't added any for about 6 months now. Is there anything that effects fish but not shrimps?
Sorry, the post got a bit long, but if anyone has any ideas I'd really appreciate it.
