Failing with Bolivian Rams
Looks like I need a little help. I am failing with my Bolivian rams. They are great for about a month, and then they fade.
I have a mature BioCube 29, with Amazon rosetta sword, driftwood with Anubias nana and the front of the tank is full of chain swords. Substrate is black coal slag (BDBS). Water changes are done weekly about 15%-25% light vac, and picking up the loose stuff on top. PH 7.4 (tank and tap), Nitrates 0, Nitrite 0, Ammonia 0, plants are growing, and dose lightly with ferts. Temp for the first 2 batches were around 80degrees, and this last batch I dropped it to 77.
I bought 3 different batches of 3 rams, two from PetSmart and one from WetSpot. All drip acclimated, etc. The females eventually hide in their favorite places and don't come out often and eventually wither and die. I got a larger male this latest round (previous ones were younger and harder to tell sex) and he's looking like he's doing great. I have a group of 9 green neon tetras as a dither and they are doing fine, except they hide a lot and only come out when I'm not near the tank.
Feeding them a variety of Golden Pearls, Hikari red sinking pellets, API flakes, BugBites once to twice a day (rotating through different foods). Also have fed them live mosquito larvae and bloodworms that I've raised about once a week. Previous batches did not get live foods (due to outside weather). They will take the bloodworms and mosquito larvae without issue as they find them. My other tanks are just fine with Tetras, Livebearers, WCMMs, shrimp, Otos, etc.
In every case, they waste away and die. I lost one female yesterday and this morning it's looking like the other one will go before tonight. Did a water change yesterday (after I found the dead fish) and tested parameters before water change and they were as above. I don't know what the deal is with this fish, but I just am not successful.
Any other ideas?
