I haven't been on in awhile to update my tank profile, but let me get this out of the way. Current Build: 30 gallon tall Stock - 1 German Blue Ram 1 Yoyo Loach 1 Adult female Guppy 3 Cardinal Tetra 4 Neon Tetra So many Ramshorn, a few bladder, 1 horned nerite Water stays between 77 -80 degrees (ac blows on one side, making it about 1-2 degrees colder). Ammonia: 0ppm Nitrite: 0ppm Nitrate: 20ishppm Ph: 6.4-6.6 K Hardness: Cement (I break it down with RO so it stays somewhere between 3-5 degrees. It comes out of the tap 10 degrees so shut up. I know it's not ideal for the ram) The female guppy is only in there because I can catch her. The tank is heavily planted and I'm not gonna tear it up to get her. Anyway, I've had the ram for about 3 months, the loach is about a month old. They are both about 3 inches long. I know the loach likes to be with others, but he doesn't seem to care and comes out a lot so whatever. Over the last few days I've noticed the loach chasing the Ram. No fin nipping or anything, but today when I got home (about 10 minutes ago) the ram and the loach were both on this piece of slate in the tank, on their bellies, and the ram seemed to be literally ramming the loach. The loach didn't move. Is this just playful behavior on both their parts? Neither seems to be nipping the other, but the Ram doesn't seem to enjoy the chasing. I've also heard that Yoyos are jumpers. Can anyone confirm that? I don't have a top on this tank because I have plants growing out of the top.
